Answer:
B. False
Explanation:
Prior to the replication of a DNA strand or molecule, the double stranded DNA molecule needs to be unwound i.e. separated into two single strands. One strand called the LEADING STRAND that runs from the 3' - 5' direction while the other strand called the LAGGING STRAND runs from the 5' - 3' direction.
The unwinding of the DNA template is carried out by an enzyme called DNA HELICASE, which binds to the DNA molecule and unwinds the double strands into two strands at the same time. This means that the unwinding into leading or lagging strand is not easier than the other since it occurs simultaneously, hence, this question is FALSE.

Answer</h2>
Buffer controls the sudden change in the solution
<h2>
Explanation</h2>
Buffer prevents the sudden change in the pH. They keep the pH of the solution nearly constant. For example, in human Buffer solution helps to regulate the pH of human blood. The normal pH of the human blood is nearly 7.35 to 7.45 and a little change in this pH many leads the serious problems. Carbonic and bicarbonate buffers play a role in maintaining the acid base balance of the blood.
