Question

The processes of DNA replication and RNA transcription in E. coli are similar in some respects and different in others.
Select the THREE statements below that describe BOTH DNA replication and RNA transcription in E. coli.

A. The direction of enzyme movement on the template strand is 3' to 5'
B. The process requires a primer.
C. The mechanism of reaction is attack by the 5'OH group of the pentose on the a-phosphate of an incoming nucleoside triphosphate.
D. A specific region of the DNA is recognized and bound by the polymerase.
E. The direction of polymerization is 5' to 3'
F. The process includes its own 3' to 5' exonuclease proofreading mechanism.

Answer 1

Answer:

The three statements that describes both DNA replication and RN transcription in E.coli are listed below.

Explanation:

C The mechanism of reaction is attack by the 5" OH group of the pentose on the alpha phosphate of an incoming nucleoside triphosphate.

A The direction of enzyme movement on the template strand is 3"→ 5.

E  The direction of polymerization is 5"→3"
