    The lagging daughter strand of DNA is synthesised in what appears to be the "wrong" direction. This synthesis is accomplished by:

    A) Ligating (connecting) short Okazaki fragments that are synthesised in short spurts in the "right" direction.

    B) Primase.

    C) Using multiple primers and DNA polymerase I.

    D) Both [a] and [b]

    Correct Answer: D

    Solution :

    [d] Okazaki fragments are short pieces of newly synthesised DNA. The production of each of these fragments is dependent on a beginning RNA primer. The small fragments are ultimately ligated connected together to form the lagging strand.
