Question

question 7 of 10
the model represents dna replication.
which statement best describes structure 2?
a. it is the leading strand because the 5’ end is closer to the replication fork.
b. it is the lagging strand because it is being built in short segments.
c. it is the lagging strand because it uses rna primers.
d. it is the leading strand because it is being built in the 3’ to 5’ direction.

Explanation:

In DNA replication, the lagging strand is synthesized in short Okazaki fragments, while the leading strand is synthesized continuously. Structure 2 shows discontinuous synthesis, indicating it is the lagging strand.

Answer:

B. It is the lagging strand because it is being built in short segments.
