Molecular Basis Of Inheritance Question 168
Question: The lagging daughter strand of DNA is synthesised in what appears to be the “wrong” direction. This synthesis is accomplished by:
Options:
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]
Show Answer
Answer:
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.
