If a chromosome unfold itself how is transportation enhanced 1.the dna region is easily accessible 2.the dna region is not accessible 3.the rna region is not accessible 4.the rna has already been made

The answers to this question are the following:Base- pairing rule where RNA was made where the U strand being paired with A-strand and the C strand being paired to G-strand in transcription within the nucleus. This is done along with the strong strand in "DNA."
The answer in the first line is "Base-pairing rule" while in the second line is "DNA"
