Determine for each statement below by listing true or false, on whether or not it is a true difference between RNA polymerase and DNA polymerase:

1) RNA pol doesn’t require a primer, DNA pol does.
2) RNA pol doesn’t have proofreading, DNA pol does.
3)RNA pol reads template 3’-->5’, DNA pol reads template 5’-->3’.
4)RNA pol adds nucleotides 3’-->5’, DNA pol adds nucleotides 5’-->3’.
5)RNA pol creates RNA, DNA pol creates DNA.
6)RNA pol template is RNA, DNA pol template is DNA.
7)RNA pol is capable of opening DNA, DNA pol is not.

Solutions

Expert Solution

And 1) The statement is true
In order to initiate replication, DNA polymerase needs primer and template. Thus to synthesize new strands RNA primers are required. Whereas, RNA polymerases do not require primer

Ans 2) The statement is False
DNA polymerases I, II and III can proofread by its 3'-5' exonuclease activity.

Ans 3) The statement is False
Both DNA polmerase and RNA polymerase require template strand in order to synthesize new strands and the direction of template strand in both case is from 3'-5'.

Ans 4) The statement is False
The synthesis of both RNA and DNA by the enzymes RNA polymerases and DNA polymerases occur in 5'-3' direction

Ans 5) The statement is True
RNA polymerase will create mRNA by the process of transcription and DNA polymerase will create DNA by the process of replication.

Ans 6) The statement is False
RNA polymerases in order to synthesize mRNA needs DNA as a template. DNA polymerase also needs the template of DNA
