  4. DThe discontinuously synthesised fragments are later joined by the enzyme DNA ligase.

Correct answer

A. For long DNA molecules, since the two strands of DNA cannot be separated in its entire length (due to very low

Step-by-step solution

For long DNA molecules, since the two strands ofDNA cannot be separated in its entire length (due to very high energy requirement), the replication occurs within a small opening of the DNAhelix, referred to as replication fork. The DNA-dependent DNApolymerases catalysed polymerisation only in one direction, that is 5' →3'.This creates some additional complications at the replication fork. Consequently, on one strand (the template with polarity 3' →5'), the replication is continuous, while on the other (the template
