Question

Why must DNA be replicated semi discontinuously?

Short answer

DNA replication: - The process of copying the DNA is called DNA replication.

Step-by-step solution

Semi discontinuously

During DNA replication the leading strand is synthesized continuously and the lagging strand is synthesized discontinuously. It is called semi discontinuous. Replication of DNA.

 Semi Discontinuous synthesis

The DNA synthesis is always in the S1 to 31 direction in both strands. The strand which is discontinuously synthesized is referred to as the ‘laggingstrand’. The one continuously polymerized is called the “leading strand”.

Simultaneously, both strands take place in replication of DNA. But it has pieces of about 100-250 nucleotides in length. In lagging the segment is joined by ligase enzymes.

Thus, DNA must be replicated semi discontinuously.
