The strand of DNA that is replicated continuously from 5’ to 3’ is known as
|
|
leading strand
|
|
|
lagging strand
|
|
|
parallel strand
|
|
|
antiparallel strand
|
Explanation:
Detailed explanation-1: -One new strand, which runs 5’ to 3’ towards the replication fork, is the easy one. This strand is made continuously, because the DNA polymerase is moving in the same direction as the replication fork. This continuously synthesized strand is called the leading strand.
Detailed explanation-2: -Leading and lagging strands DNA is made differently on the two strands at a replication fork. One new strand, the leading strand, runs 5’ to 3’ towards the fork and is made continuously. The other, the lagging strand, runs 5’ to 3’ away from the fork and is made in small pieces called Okazaki fragments.
