Question
- A. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches DNA and the genome because students must describe DNA as the genetic material in the nucleus of a cell.
- B. Reversed contrast: Calling a gene a whole chromosome. This would blur DNA vs genes instead of testing DNA and the genome.
- C. Over-broad contrast: Explaining protein coding without naming the gene as the relevant section of DNA. This misses the objective focus on describe DNA as the genetic material in the nucleus of a cell.
- D. Unrelated contrast: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / DNA and the genome.
Answer
The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches DNA and the genome because students must describe DNA as the genetic material in the nucleus of a cell.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in DNA and the genome.
Explanation
The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches DNA and the genome because students must describe DNA as the genetic material in the nucleus of a cell.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches DNA and the genome because students must describe DNA as the genetic material in the nucleus of a cell. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must describe DNA as the genetic material in the nucleus of a cell, so the answer must stay inside DNA and the genome. 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
Misunderstanding DNA Location
Students often confuse DNA as being located in the cytoplasm instead of the nucleus.
Remember that DNA is specifically found in the nucleus of eukaryotic cells, which is where it serves as the genetic material.
