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. only a small area is opened. it makes a copy of itself.

Explanation:

During transcription, only a small region of the DNA molecule unwinds to allow the synthesis of RNA. DNA does not open up all the way one gene at a time (it's a small area), it doesn't unwind from both ends (unwinding is local), and making a copy of itself is replication, not transcription.

Answer:

Only a small area is opened.
