Question

Which of the parent DNA strands is replicated discontinuously?

the lagging strand
the leading strand
the helicase strand
the polymerase strand
the daughter strand

Answer 1

the lagging strand

Step-by-step explanation:

The two types of DNA strands are leading and lagging. Although both these strands involve the help of enzymes such as helicase and DNA polymerase, the leading strand is made continuously. After an RNA primer is laid complementary to the DNA template strand by primase, DNA polymerase continues to add successive nucleotides.

The lagging strand, which runs in the direction away from the closest replication fork, has to be made in fragments known as Okazaki fragments. After DNA polymerase hits the next primer while running in the 5' to 3' direction, it has to disconnect and reattach itself to the next RNA primer.
