Select all the correct answers.<br> Which two statements are true for the leading strand in DNA?
Ghella [55]

Question: Which two statements are true for the leading strand in DNA?

It is synthesized toward the replication fork.

It is synthesized in the 3′ to 5′ direction.

It is synthesized away from the replication fork.

It is synthesized in the 5′ to 3′ direction.

Answer:

The two statements that are true for the leading strand in DNA are "it is synthesized toward the replication fork and it is synthesized in the 5′ to 3′ direction"

Explanation:

Leading strand in DNA is the strand of new DNA being synthesized in the same direction where the replication fork is moving. The movement of replication fork allows the access of template for the new DNA. The DNA synthesis is continuous in the leading strand. It is synthesized in the 5' to 3' as DNA synthesis always takes place in this direction. This is because dNTP ( deoxyribonucleoside triphosphate) provides free 3' OH group where new dNTP can be added by the enzyme DNA polymerase.
