DNA is a nucleic acid molecule that undergoes a replication process to form a new daughter strand. The blue segment is the parental strand, and the yellow is the daughter strand.

<h3>What is replication?</h3>

Replication is the process of the central dogma that duplicates the copy of the parent strand into new daughter strands. The two helixes of the parent strand get separated to make the complimentary copy of the new strand.

The daughter DNA is semi-conservative and are complementary structure made from the duplication of the parent strand with the help of the replication enzymes.

Therefore, the daughter strands are the semi-conservative copies of the parental strand.
