rusak2 [61]

Answer:

B) Polymerases can only synthesize in the 5' to 3' direction

Explanation:

The leading strand's directionality is 3' to 5', so polymerase has no problem with replicating this one. But the lagging strand has the opposite directionality, so the polymerase must work in the opposite direction of the replication fork.In consequence, the replication process undergoes periodic breaks, and the enzymes have to stop and start again while helicase separates both strands, resulting in the polymerization of okazaki fragments.

If i show a dominant trait do one of my parents have to show the same trait? explain?​
Mama L [17]
