Question

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

Explanation:

During transcription, only a small region of the DNA molecule (the gene - containing region) is opened up. It doesn't open up all the way one - gene at a time, nor unwind from both ends, and making a copy of itself is replication, not transcription.

Answer:

D. Only a small area is opened
