Explanation / Answer

Ans 1:

A) mitosis

Explanation: the role of DNA polymerase is to replicate a DNA molecule into two. DNA replication takes place during S phase of mitosis , and not in translation or transcription or meiosis II.

Dna replication takes place in meiosis I.

2- C: translation

3- A: Transcription

4-C : translation

5- D: tRNA

7- E : all need complimentary base pairing

8: E: two daughter cells
