Question 5
The structure of a DNA replication fork is best represented by: A. B. C. D.
Worked Solution & Example Answer:The structure of a DNA replication fork is best represented by: A - VCE - SSCE Biology - Question 5 - 2010 - Paper 1
Step 1
Identify the Correct Structure
Answer
A DNA replication fork consists of two strands separating to allow for replication. This structure is characterized by the directionality of the strands, which run antiparallel to each other. In the replication fork, one strand will be oriented in the 5' to 3' direction, while the other runs in the 3' to 5' direction.
Step 2
Choose the Appropriate Diagram
Answer
Based on the descriptions of the DNA strands, option B best represents the structure of a DNA replication fork. In option B, the orientations of both strands are clearly indicated, with one running from 5' to 3' and the other from 3' to 5', accurately depicting a replication fork.
