Question

which statement is true about the dna molecule during transcription?
it makes a copy of itself.
it opens up all of the way, one gene at a time.
it unwinds from both ends.
only a small area is opened.

Explanation:

• DNA replication involves making a copy of itself, so the first option is incorrect.
• During transcription, only a small area of the DNA molecule unwinds and opens (the gene being transcribed), not the entire molecule or from both ends. So the second and third options are incorrect.
• The fourth option is correct as only a small area (the specific gene region) is opened during transcription.

Answer:

Only a small area is opened.
