A helicase enzyme unwinds the DNA molecule, then corresponding nucleotides are added to the separated original strands forming two semi-conservative molecules - best describes that genetic information is conserved during replication process.
Explanation:
The process of DNA replication is semi-conservative, where each of the strand of the double helix DNA replicates itself to form two daughter helices, each with one parental helical strand or content.
The parent strands acts as the template for daughter helices formation and their genetic information are conserved and stored in the daughter helices.
DNA helicase is an essential enzyme which takes part in DNA replication. Its major role is to begin the conservation replication by unwinding each of the strands of the coiled DNA double helix strand. This unwinding will open the double helix into a Y-shape.
Later other enzymes RNA primase, DNA polymerase, and DNA ligase further works in the replication process which proceeds with addition of corresponding nucleotides to the strands and linking of the leading and lagging strands.
