Question

Arrange the following events for the synthesis of RNA in the correct order:1) Nucleophilic attack of the 3′ OH group of the first nucleotide at the α-phosphate group of the second nucleotide 5′ triphosphate occurs.2) Template specific rNTPs are bound.3) Several DNA bases are unwound, forming a stable complex.4) Polymerase finds a promoter region.5) A Mg+2-dependent isomerization of DNA takes place.Options:a) 4, 2, 3, 5, 1b) 4, 3, 2, 5, 1c) 4, 1, 3, 2, 5d) 4, 3, 5, 2, 1

Answer 1

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

Step-by-step 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.
