Worked Solution & Example Answer:During meiosis, homologous chromosomes pair as shown in the following diagram - VCE - SSCE Biology - Question 13 - 2005 - Paper 1
Step 1
The number of DNA molecules this pair of chromosomes contains is
Answer
To determine the number of DNA molecules in the pair of homologous chromosomes, we need to understand that each chromosome consists of a single DNA molecule. In the diagram, the pairing indicates that there are two homologous chromosomes.
Given that each chromosome has one DNA molecule, for a pair of homologous chromosomes:
Number of DNA molecules = 2 (one from each chromosome).
Therefore, the correct answer is D. two.
