Question

Select the correct answer from each drop-down menu.
During DNA replication, the ___ (Lagging, Okazaki, Leading.) strand is synthesized in the 5′ to 3′ direction. The strand that runs away from the replication fork is synthesized in ___ (In Fragments, By RNA polymerase, Continuously, Without Primers.) because ___ (DNA polymerase cannot synthesize in the 5' to 3' direction, RNA polymerase can only add primers to the lagging strand, RNA polymerase can only add primers to the leading strand, DNA polymerase cannot synthesize in the 3' to 5' direction.)

Answer 1

Hello there!

During DNA replication, the Leading strand is synthesized in the 5′ to 3′ direction. The strand that runs away from the replication fork is synthesized In Fragments because DNA polymerase cannot synthesize in the 3' to 5' direction.

The fragments formed are called Okazaki fragments. These fragments are then connected to each other through the enzyme ligase.

I hope this will help you!

Answer 2

While replicating the DNA, Leading strand will be synthesized in the 5′ to 3′ direction.

The strand that runs away from the replication fork is synthesized In Fragments because DNA polymerase cannot synthesize in the 5' to 3' direction.

The fragments that are built are known as Okazaki fragments.

Each of the fragments is closely coupled with the other one with the help of enzyme ligase.
