The development of understanding of genetics and evolution

Question

A. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Theory of evolution (biology only) because students must explain that the mechanism of inheritance and variation was not known when Darwin published his theory.
B. Reversed contrast: Calling a gene a whole chromosome. This would blur DNA vs genes instead of testing Theory of evolution (biology only).
C. Over-broad contrast: Explaining protein coding without naming the gene as the relevant section of DNA. This misses the objective focus on explain that the mechanism of inheritance and variation was not known when Darwin published his theory.
D. Unrelated contrast: It moves into a neighbouring Unit 4.6 idea rather than The development of understanding of genetics and evolution / Theory of evolution (biology only).

Answer

Explanation

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Theory of evolution (biology only) because students must explain that the mechanism of inheritance and variation was not known when Darwin published his theory.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Theory of evolution (biology only) because students must explain that the mechanism of inheritance and variation was not known when Darwin published his theory. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must explain that the mechanism of inheritance and variation was not known when Darwin published his theory, so the answer must stay inside Theory of evolution (biology only). The alternative options are wrong because they either calling a gene a whole chromosome., explaining protein coding without naming the gene as the relevant section of dna., or drift away from when asking about genes, test a section of dna, protein coding, alleles, or inherited characteristics..

Common mistake

Theory of evolution (biology only) common mistake 1

Giving a vague answer instead of directly addressing: Explain that the mechanism of inheritance and variation was not known when Darwin published his theory..

Answer by clearly explaining how to explain that the mechanism of inheritance and variation was not known when Darwin published his theory..
