Genetics Mini-Game Demo

Eight interactive mini-games, each teaching a genetics concept. This page demonstrates every mini-game archetype available in the platform.

1. Gene Expression Pipeline

Follow the central dogma of molecular biology step by step. DNA is transcribed into mRNA, which is then translated into a protein. Watch each molecule change as you step through.

Interactive
From DNA to Protein

Tap Step to advance one line at a time.

1dna = "ATGCGATAA"
2mrna = transcribe(dna) # A->U, T->A, G->C, C->G
3codons = split_codons(mrna) # groups of 3
4protein = translate(codons) # codon -> amino acid
5print(protein)

step: 0/5 | active_line: none | variables: {} | output: []

2. Biomolecule Classification

Drag each molecule into the correct category. See how the same chemical building blocks serve different roles in living systems.

Interactive
Sort the biomolecules

Drag each item into the column where it belongs.

Glucose
Hemoglobin
DNA
Cholesterol
Insulin
Starch
tRNA
Carbohydrate
drop here
Protein
drop here
Nucleic Acid
drop here
Lipid
drop here
Place every item to check your answer.
Glucose: unplaced | Hemoglobin: unplaced | DNA: unplaced | Cholesterol: unplaced | Insulin: unplaced | Starch: unplaced | tRNA: unplaced

3. Chromosome Inheritance

Watch how chromosomes are passed from parents to offspring during reproduction. Each parent contributes one copy of each chromosome.

Interactive
Meiosis and inheritance

Tap Step to watch what happens in memory, one action at a time.

Code
▸Mother has chromosome pair: [A1, A2]
▸Father has chromosome pair: [A3, A4]
▸Meiosis: Mother contributes A1, Father contributes A4
Names
Mother
→
[Chromosome A1, Chromosome A2]
Father
→
[Chromosome A3, Chromosome A4]
Child
→
[Chromosome A1, Chromosome A4]
Objects in memory
[Chromosome A1, Chromosome A2]
pointed to by: nobody
[Chromosome A3, Chromosome A4]
pointed to by: nobody
[Chromosome A1, Chromosome A4]
pointed to by: nobody
The child gets A1 from mom and A4 from dad. This is random - it could have been A2 and A3, or any other combination. This randomness is why siblings are different.
step: 0/3 | action: none | names: {} | objects: {}

4. Phases of Mitosis

Cell division follows a precise sequence. Put the phases of mitosis in the correct order.

Interactive
Order the phases of mitosis

Drag the lines into the correct order, then tap Check.

1Prophase: chromosomes condense, spindle forms
2Interphase: cell grows and copies its DNA
3Cytokinesis: the cell physically splits into two
4Telophase: nuclear envelopes reform around each set
5Anaphase: sister chromatids are pulled apart
6Metaphase: chromosomes line up at the center
order: ["Prophase: chromosomes condense, spindle forms","Interphase: cell grows and copies its DNA","Cytokinesis: the cell physically splits into two","Telophase: nuclear envelopes reform around each set","Anaphase: sister chromatids are pulled apart","Metaphase: chromosomes line up at the center"] | correct: false | checked: no

5. Genetics Vocabulary

Match each genetics term to its definition. These are the building blocks of understanding heredity.

Interactive
Match the term to its meaning

Tap a left card, then tap the right card it matches.

Genotype: unmatched | Phenotype: unmatched | Allele: unmatched | Homozygous: unmatched | Heterozygous: unmatched | Dominant: unmatched

6. From Gene to Trait

Follow a gene through each stage of expression, from DNA sequence all the way to an observable physical trait.

Interactive
Gene expression pipeline

Tap to reveal each stage of the pipeline in turn.

MC1R gene (DNA)
→
input: MC1R gene (DNA) | stages_active: 0/5 | current_result: MC1R gene (DNA) | pipeline: empty

7. Spot the Mutation

A DNA sequence has been copied, but a mutation crept in during replication. Find the line where the error occurred.

Interactive
Find the replication error

This code has one bug. Tap the line you think is wrong.

1Original: A T G C G A T A A
2Copy: A T G C G A T A A
3 | | | | | | | | |
4Complement: T A C G C T A T T
5Replicated: T A C G G T A T T

7 error here?
found: false | bug_line: 5 | attempts: 0

8. Punnett Square Predictions

In a cross between two heterozygous parents (Bb x Bb), predict whether each offspring genotype will show the dominant phenotype (brown eyes) or the recessive phenotype (blue eyes). Brown (B) is dominant over blue (b).

Interactive
Will the offspring have brown eyes?

Tap each Result cell to cycle True / False, then tap Check.

Brown eyes = at least one B allele (dominant)
Parent 1 alleleParent 2 alleleOffspring genotypeResult
BBBB
BbBb
bBbB
bbbb
row0(B,B,BB): guess=null answer=true | row1(B,b,Bb): guess=null answer=true | row2(b,B,bB): guess=null answer=true | row3(b,b,bb): guess=null answer=false

Result: 3 out of 4 offspring (75%) show the dominant trait. Only bb (25%) shows the recessive trait. This is the classic 3:1 Mendelian ratio.
