MHT CET Biology question

Identify the incorrect difference from the following given difference between leading and lagging strand.

(A)Leading strand: It grows continuously as a single piece. Lagging strand: It is formed initially as short segments, called Okazaki segments.
(B)Leading strand: It needs a single RNA primer to start its growth. Lagging strand: Each segment needs a separate RNA primer to start growth.
(C)Leading strand: It does not need DNA ligase. Lagging strand: DNA ligase is needed to join Okazaki fragments.
(D)Leading strand: Direction of growth is 3′ → 5′. Lagging strand: Direction of growth of each Okazaki fragment is 3′ → 5′.Correct

Answer: (D)

Solution

(a), (b) and (c) are correct differences, whereas in (d) both the leading strand and every Okazaki fragment
