A) Protein kinases are needed to initiate replication
B) Polymerase switching occurs during replication
C) Six different forms of DNA polymerase have been isolated

Answer 1

Answer

1. Option D is the right answer because GTP is used as energy source in protein synthesis.

2. Option A is the right answer

3. Option A is the right answer

4. Option A is the right answer because Exon never edited in pre-mRNA complex before translation

5. Option D is the right answer  

6. Option D is the right answer
