DNA Explorer
Build and copy DNA strands, then read them as mRNA codons.
DNA Explorer starts with the picture of the double helix and asks students to name its parts, such as the sugar, phosphate, base and the rungs that join the two strands. Next comes base pairing: A with T and C with G. Children fill in the missing base, spot a rung that breaks the rules, and write the matching strand from left to right.
Once the pairing rules feel natural, the game counts things in a piece of DNA, like base pairs, nucleotides and hydrogen bonds, and then looks at copying. Students see how a molecule is copied, how many old strands each new molecule keeps, and how DNA becomes mRNA, codons and a chain of amino acids.
What children practice
- Name the sugar, phosphate and base in a nucleotide
- Apply A-T and C-G base pairing to complete strands
- Count base pairs, nucleotides and hydrogen bonds in DNA
- Explain how DNA replication keeps one old strand in each copy
- Write the mRNA strand that matches a DNA template
- Use a codon table to find amino acids and start or stop
Levels
- Level 1: Name the DNA parts
- Level 2: Base pairing
- Level 3: Complementary strands
- Level 4: DNA facts
- Level 5: Copying DNA
- Level 6: mRNA and codons
How it works
- Six levels move from naming the parts to mRNA and codons.
- After five correct answers and a short practice timer, the next level opens.
- When an answer is wrong the game asks your child to try again.
- Questions can be read aloud, and a correct answer shows a short explanation.
Best for: A good fit for grades 7 to 10 when students are first learning DNA structure or reviewing base pairing and protein synthesis.
Tip for parents: Ask your child to write a short DNA strand on paper and have you write its partner strand. Swapping roles lets them check the pairing rules by teaching them.
Questions parents ask
Does DNA Explorer teach how proteins are made?
It introduces the first step. Level 6 shows a DNA template, asks for the matching mRNA, and uses a codon table to find amino acids and the start and stop codons. It does not cover the full process of building a protein.
Is the base pairing practice only multiple choice?
Questions are multiple choice, but they use drawn strands. Children fill in a missing base, find a rung that does not follow the rules, or pick the complementary strand. This makes them apply the pairing rules instead of just reciting them.
What does the game say about copying DNA?
Level 5 shows a molecule being copied and asks what the two new molecules look like. Students also identify the new strand, find how many old strands each copy keeps, and count molecules after several rounds of copying.
