Question

which statement is true about dna?
its replication takes place in the cytosol.
only one of the original dna strands acts as a template during replication.
both of the original dna strands act as templates during replication.
it is a single - stranded molecule.

Explanation:

• DNA replication occurs in the nucleus (not cytoplasm), so the first option is wrong.
• DNA is double - stranded (not single - stranded), so the fourth option is wrong.
• During DNA replication, both of the original DNA strands act as templates (semi - conservative replication), so the second option is wrong and the third option is correct.

Answer:

Both of the original DNA strands act as templates during replication.
