Just took the quiz the answer is:
"Both of the original DNA strands act as templates during replication."
Both of the original DNA strands act as templates during replication is the statement that is true about DNA.
DNA is a macromolecule made up of repetitive nucleotide units, that is, it is made up of multiple simple units that are related to each other, forming a chain.
Replication is the process by which cells synthesize an identical copy of a DNA molecule, using existing DNA as a template for new DNA strands.
That is, in DNA replication, an original double-stranded DNA molecule is converted into two identical daughter DNA molecules.
When replication begins, the two chains unwind and separate from each other in a small segment of the molecule.
Uncoiling of the double helix and keeping the two strands apart is possible by various specialized proteins such as helicases unwinding short DNA fragments ahead of the replication fork.
Therefore, we can conclude that both of the original DNA strands act as templates during replication is the statement that is true about DNA.
