In DNA replication, continuously synthesis occurs on the leading strand Multiple choice question. toward the origin of replicati
Tamiku [17]

Answer:

toward the origin of replication

Explanation:

DNA is always synthesized in the 5' to 3' direction, thereby DNA can be synthesized continuously on the leading strand, because the growth of this strand proceeds in the same direction as the movement of the replication fork, while DNA synthesized in several short segments on the lagging strand which are called 'Okazaki fragments'. DNA polymerases are enzymes that can only add nucleotides to the 3' end of a DNA strand, thereby they require the synthesis of short stretches of RNA or 'RNA primers', which are necessary for DNA replication of the lagging strand.
