Interactive Worksheets — mRNA Vaccine, Six Classes

Class 1 60 min

Understanding how mRNA vaccines work, through videos

mRNA is a "protein blueprint note" sent to the cell. Follow the six steps (design → packaging → cell entry → translation → immune training → natural breakdown) through short videos, and write one answer after each. Reference: theory slides (PDF, Korean)

Goal 1State the flow DNA → mRNA → protein

Goal 2Explain why the LNP is needed and how it escapes the endosome

Goal 3Answer "mRNA changes your DNA" with science

1Why learn this 5 min

In 2020, humanity obtained a new kind of vaccine in a single year. Yet many people were afraid to take it. "It changes my DNA." "It was made too fast to be safe." "Something stays in my body." The same stories went around in Tanzania and in Korea. The root of the fear was mostly not knowing the principle. Today's goal is to understand that principle well enough to explain it to a friend.

Warm-upWrite down one thing you have heard about mRNA vaccines (a rumour, news, something a family member said). You do not need to know yet whether it is true.

2What a cell is made of: the four biomolecules 5 min

No biology or chemistry background needed. Only four kinds of molecule matter for understanding the vaccine. As the figure on the left shows, functional groups (–OH, –COOH, –NH₂, –PO₄ …) attached to a carbon skeleton give four large molecules, and chemical structure creates biological function.

Chemical structure to biological function — carbohydrates, proteins, nucleic acids, lipids — From chemical structure to biological function: carbohydrates · proteins · nucleic acids · lipids (theory deck p. 5, figure: biologynotesonline.com)

1Nucleic acids (DNA · RNA)Information. Nucleotides link into a chain whose base sequence stores the message.Today's hero: the mRNA itself

2ProteinsWorkers. Chains of amino acids fold into enzymes, receptors and antibodies.The "antigen" the vaccine makes the cell build

3LipidsMembranes. A phospholipid bilayer builds a wall between water and water.The LNP wrapping around the mRNA

4CarbohydratesEnergy and structure. Sugars join into chains and branches.Tags on the cell surface · energy

Two of them are today's main characters. Nucleic acid: the mRNA itself. Lipid: the wrapping that carries the mRNA to the cell. And the product is a protein, the antigen. Every scene that follows is the work of these three molecules.

Q0. The LNP that wraps the mRNA and carries it to the cell is made of which of the four biomolecules?

Nucleic acid Carbohydrate Lipid

ConnectPair each of the four biomolecules with its role in the mRNA vaccine, one line each. (nucleic acid = ?, protein = ?, lipid = ?, carbohydrate = ?)

3The central dogma: from blueprint to protein 10 min

What the nucleus does24 s · DNA is the original book in the nucleus

The nucleus keeps the original (DNA) and copies only the pages it needs as mRNA, which leaves the nucleus.

Ribosome translation animation10 s · the factory that reads the note

The ribosome reads one codon (three bases) at a time while tRNA brings the matching amino acid and links it on.

DNA	mRNA	Ribosome	Protein
The original book in the nucleus	A note copying only the needed page (transcription)	The factory that reads the note (translation)	The finished worker · the antigen

Key 1 mRNA is a temporary note. It is broken down and recycled within days.
Key 2 mRNA does not enter the nucleus. It is read only in the cytoplasm, outside the nucleus.
Key 3 Information flows DNA → RNA → protein. Vaccine mRNA does not change DNA.

Q1. Where is vaccine mRNA read and turned into protein?

Inside the nucleus, next to the DNA At ribosomes in the cytoplasm, outside the nucleus By itself, in the blood

4How an mRNA vaccine works, at a glance 10 min

The principle of the mRNA vaccine30 s · send only the blueprint

Instead of the virus, only the blueprint of the antigen protein is sent. Our own cells make the antigen and the immune system memorises its face.

Dendritic cells and T-cell training1 min 57 s · from packaging to immune memory

LNP → dendritic cell → antigen presentation → T- and B-cell training → memory. All six steps in one video (Korean narration).

After watchingIn one sentence, what is the biggest difference between traditional vaccines (attenuated or inactivated) and an mRNA vaccine? Hint: what is put into the body?

After watchingWrite the six steps from the second video in order. (design → … → natural breakdown)

5Packaging: the lipid nanoparticle (LNP) 10 min

Structure of the LNP15 s · four lipids

Ionizable lipid · phospholipid · cholesterol · PEG-lipid. Naked mRNA is cut by RNases in the body within minutes.

Why the ionizable lipid is special2 min 54 s · its charge changes with pH

At pH 4 it is positively charged and holds the mRNA; in blood (pH 7.4) it is neutral; in the acidic endosome it turns positive again, breaks the membrane and gets out.

Q2. Why does the LNP release its mRNA only inside the endosome?

Because the endosome cuts the LNP with scissors Because the endosome is hot and melts the lipid Because when the endosome turns acidic, the ionizable lipid becomes positively charged and breaks the membrane

6Cell entry → translation → immune training 15 min

mRNA release: endosomal escape30 s · success rate 1–2%

Endocytosis → acidification (pH 7.4 → 4–5) → membrane disruption → escape. Too late and the lysosome digests everything.

Macrophage vs dendritic cell1 min 4 s · the sentinels of immunity

The dendritic cell samples → senses → migrates → presents. It is the teacher that shows the antigen to T cells.

A T cell wakes up only with three signals

Signal 1	peptide-MHC ↔ TCR: "is this the right enemy?"
Signal 2	CD80/86 ↔ CD28 co-stimulation: "is it dangerous?"
Signal 3	cytokines: "what kind of T cell should I become?"

Why your arm hurts and you feel feverish after the shot: it is the sign that the immune system is training. Lymph nodes swell because one T cell is multiplying into thousands (clonal expansion).

Q3. What happens if the dendritic cell shows the T cell only the antigen (signal 1)?

The T cell activates at once and attacks the cancer The T cell falls asleep (anergy) and does not activate The T cell turns into a B cell

Class 2: Design the vaccine →

Class 2 60 min

Designing an mRNA vaccine: DNA sequence → find the mutation → design the mRNA → synthesis

A personalised cancer vaccine is made in four steps: read the patient's tumour DNA, find mutations (neoantigens) that normal cells lack, write them into a blueprint (mRNA), then synthesise it in a test tube and pack it into LNPs. It is the very road Paul walked for Rosie in Coding for Rosie. Reference: theory PDF pages 19, 23, 24; practice PDF page 8 (the "ribosome slot machine" example); novel chapters 6–8 (Korean).

Goal 1Find a mutation by comparing normal and tumour DNA

Goal 2Use the codon table to read the amino acid the mutation changed (the neoantigen)

Goal 3Design the seven mRNA parts in 5′→3′ order and explain synthesis

1DNA sequencing data: inside 200 gigabytes 10 min

A sequencer reads the DNA of tumour tissue and of normal tissue (blood) in millions of fragments and writes them to files. Paul received four files for Rosie (tumour and normal, two each), 200 gigabytes in all. Software aligns both sequences to the reference genome and looks for differences present only in the tumour (variant calling, for example with Mutect2). Paul got 4,847 candidates; choosing the ones the immune system could recognise was the next task.

ThinkWhy must the DNA of normal tissue (blood) be read too, and not just the tumour DNA? Recall the novel's chapter 6, "Why two were read".

2Find the mutated gene yourself 15 min

Below is the beginning of the human KRAS gene (codons 1–18). The top row was read from normal cells, the bottom row from tumour cells. Click the codon that differs in the tumour row.

Normal (blood)

Tumour — click the changed codon

Read it with the codon table: three bases = one amino acid

When a DNA codon is copied into mRNA, T becomes U. Use the small (partial) codon table below.

mRNA codon	Amino acid	mRNA codon	Amino acid
GGU · GGC · GGA · GGG	Glycine (Gly, G)	GAU · GAC	Aspartate (Asp, D)
GUU · GUC · GUA · GUG	Valine (Val, V)	GCU · GCC · GCA · GCG	Alanine (Ala, A)
AUG	Methionine (Met, M) · start	UAA · UAG · UGA	stop

Normal codon 12 (DNA: GGT → mRNA: ?)

Tumour codon 12 (DNA: GAT → mRNA: ?)

Amino acid change

KRAS G12D really is one of the most common mutations in pancreatic and colorectal cancer. When the short peptide containing the mutated position, VVVGADGVGK, is displayed on the tumour cell's MHC, it becomes a "neoantigen" that normal cells do not have. This is the "enemy's face" the vaccine will teach.

Q1. Among 4,847 candidates, which mutation makes a good vaccine target?

One producing a protein that normal cells also have in abundance One found only in cancer cells, whose fragment binds MHC well so T cells can recognise it The longest one in the DNA

3Design the mRNA: seven parts, 5′→3′ 15 min

The blueprint of the neoantigen peptide (the ORF) alone will not be read by the cell. Without a cap and a tail, the cell treats it as an intruder and degrades it at once. Click the parts in 5′ → 3′ order to assemble the mRNA.

5′

Part	Role	In vaccine design
5′ cap	protective hat · handle for the ribosome	no cap → immediate degradation
5′ UTR	introduction (not translated)	a stable UTR borrowed from the globin gene
AUG + signal peptide	start codon and "delivery address"	routes the antigen into the MHC pathway
ORF (antigen)	coding sequence = antigen blueprint	several neoantigens joined together
stop codon	UAA · UAG · UGA	without it the ribosome cannot stop
3′ UTR	closing words · lifetime control	a stable UTR extends the lifetime
poly(A) tail	AAAA… stability	when the tail wears down, degradation begins

One more thing: uridine (U) is swapped for a modified nucleoside (pseudouridine, m1Ψ) so the cell's RNA sensors (TRIM25 and others) do not treat the mRNA as an intruder. The 2023 Nobel Prize in Physiology or Medicine (Karikó and Weissman) was awarded for exactly this discovery.

DesignInstead of codons 1–18 as they are, the ORF is built by joining several neoantigen peptides. Write a design memo for our patient's ORF, including the mutation you found in step 2.

4Synthesising the vaccine: in-vitro transcription and LNP packaging 15 min

The designed sequence is made into a plasmid DNA template, and in a test tube RNA polymerase synthesises the mRNA in bulk (in-vitro transcription, IVT). No cells or viruses need to be cultured. After purification and quality control, the mRNA meets the lipids in a microfluidic mixer and becomes LNPs. Click the steps in order.

Structure of the LNP (review)15 s

When the four lipids dissolved in ethanol meet the mRNA in pH 4 buffer inside the mixer, the positively charged ionizable lipid grabs the mRNA and the whole thing self-assembles into 100 nm particles.

Kinds of endocytosis1 min 30 s · preview of the next class

How the finished LNP gets into a cell. In class 3 you will go in yourself as the nanoman.

Q2. In the microfluidic mixer, what flow ratio and speed are used for buffer (mRNA) and ethanol (lipids)?

Buffer 3 : lipids 1, fast (more than 10 mL per minute) Buffer 1 : lipids 3, slowly The ratio does not matter as long as you stir for a long time

Q3. Why must the buffer holding the mRNA be pH 4 (acidic)?

Because mRNA grows longer in acid Because acid kills bacteria Because in acid the ionizable lipid is positively charged and holds the negatively charged mRNA

2My own game scenario: a one-page plan 20 min

Start small, go deep. A game that handles one or two science steps accurately beats one that skims all six. The format may be a game, a play or a novel.

Science step	As a scene or rule	Enemy · danger
① Design and assembly	A puzzle putting the 7 parts in 5′→3′ order	Wrong order and the ribosome cannot read it
② LNP packaging	Matching the ratio of 4 lipids, running the mixer	RNases cut naked mRNA
③ Cell entry and escape	Timing on the pH gauge	Too late: lysosome; too early: failure
④ Translation	Matching codons to amino acids	A time limit as the poly(A) tail wears down
⑤ Antigen presentation and T cells	Matching key (antigen) to lock (TCR), three signals	With only one signal the T cell falls asleep
⑥ Attacking the tumour	Telling cancer cells from normal cells and attacking	PD-L1 shield → break it with the antibody

5Looking back: from learner to teacher

Science must be accurate to be passed on. The fear of the pandemic came from not knowing. The app we built passes on the accurate principle simply.
AI is a tool. What to build, whether the science is right and whether it is fun are decided by people. A prompt is the result of thinking.
You learn best by teaching. Send the link to your family and explain it. If you can explain it, you really know it.
