Question

okazaki fragments select one: a. elongate the lagging strand away from replication fork 5' --> 3' b. elongate the leading strand toward replication fork 5' --> 3' c. elongate both strands, but do the lagging strand more slowly d. elongate the lagging strand toward the replication fork 5' --> 3'

Answer 1

The Okazaki fragment moves the lagging strand away from the replication fork 5' --> 3'.

What does Okazaki Fragment do?

• Okazaki fragments are small stretches of DNA formed during discontinuous lagging strand synthesis during DNA replication. They are important because they allow the synthesis of both daughter strands required for cell division.
• DNA polymerases are enzymes involved in DNA replication. It synthesizes DNA only in the 5'-3' direction. However, double-stranded DNA is antiparallel, so DNA synthesis should occur in both directions. Thus, Okazaki fragments are formed during synthesis of the lagging template strand.

What is difference between leading and lagging strands?

The main difference between leading and lagging strands is that the leading strand is the DNA strand that grows continuously during DNA replication whereas the lagging strand grows discontinuously by forming short segments known as Okazaki fragments.
