Question

The origin of replication is best described as:

Options

• A specific DNA sequence in a chromosome that initiates DNA replication

• The point where two DNA strands separate during transcription

• The terminal region of a chromosome where genes are inactivated

• An enzyme that synthesizes new DNA during cell division

Answer 1

In a chromosome, there is a specific DNA sequence called the origin of replication. The origin of replication initiates replication. Therefore, for the multiplication of any alien piece of DNA, it must become associated with a DNA sequence having an origin of replication so that it can replicate and multiply in the host organism.
