Question

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

Explanation:

During transcription, RNA polymerase binds to a specific region of DNA (the promoter) and only a small segment (the gene being transcribed) is unwound and opened, not the entire DNA or from both ends. DNA replication is when DNA makes a copy of itself, not transcription. So the correct statement is "Only a small area is opened."

Answer:

Only a small area is opened.
