Question

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

Explanation:

• DNA is double - stranded. So, the statement "It is a single - stranded molecule" is false.
• During DNA replication, both of the original DNA strands act as templates. So, the statement "Only one of the original DNA strands acts as a template during replication" is false.
• DNA replication takes place in the nucleus (in eukaryotes) or in the nucleoid region (in prokaryotes), not in the cytosol. So, the statement "Its replication takes place in the cytosol" is false.

Answer:

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