How is mrna transcribed without disrupting a dna molecule?
a. just like dna synthesis, mrna synthesis is done along small sections of dna that are uncoiled and the two strands separated.
b. once the mrna is created from one of the dna strands, that portion of the dna rejoins and recoils as more dna opens up further down.
c. in this way a continuous strand of mrna can be synthesized without uncoiling a long sequence of dna and separating the two strands.
d. only separating a small portion of the dna at a time reduces the probability of damage to the molecule.
