Johanna Humphrey · Answer 1

Answer: the correct answer is D 4, 3, 5, 2, 1

Explanation:

the correct steps in RNA synthesis are:

4) The polymerase finds a promoter region.

3) Several DNA bases uncoil, forming a stable complex.

5) A Mg + 2 dependent DNA isomerization occurs.

2) Template specific rNTPs are linked.

1) A nucleophilic attack of the 3'OH group of the first nucleotide occurs on the α-phosphate group of the second nucleotide 5 'triphosphate.
