In prokaryotes, the process of replication is catalysed by the following enzymes. Identify which of the enzymes is best coordinate with the role.

The main enzyme for DNA replication is

(1)DNA-dependent RNA polymerase

(2) RNA-dependent DNA polymerase

(3) DNA-dependent DNA polymerase

(4) RNA-dependent RNA polymerase

The energy for the DNA replication comes from

(1)Deoxyribonucleosides triphosphates

(2) Deoxyribonucleotides triphosphates

(3) Deoxyribonucleosides

(4) phosphorylation of ATP

Which of the following is incorrect for DNA polymerase?

1. template dependent enzyme

2. highly efficient enzyme

3. high degree of accuracy

4. template independent enzyme

which of the following purposes are not served by Deoxyribonucleoside triphosphates

(1) act as substrate

(2)act as energy source for replication

(3)act as enzyme cofactors

(4)act same as ATP

Circular DNA is found in:
(1) Viruses

(2) Bacteria, chloroplast and mitochondria

(3) Chloroplast and mitochondria alone

(4) All of these

Bacterial nucleoid has:

(1) One single-stranded DNA            

(2) One double-stranded DNA

(3) Two single-stranded DNA             

(4) Many double-stranded DNAs

Column-I                           Column-II
I. Termination                    A. Aminoacyl tRNA synthetase
II. Translation                    B. Okazaki fragments
III. Transcription                C. GTP dependent release factor
IV. DNA replication            D. RNA polymerase
The correct match is:
(1) I - B, II - A, III - C, IV - D           

(2) I - C, II - A, III - D, IV - B

(3) I - D, II - C, III - A, IV - B           

(4) I - B, II - C, III - A, IV - D

DNA polymerase:
A. Is the main enzyme for RNA synthesis
B. Is DNA dependent DNA polymerizing enzyme
C. Is a highly efficient enzyme
D. Is catalyzes a reaction with a high degree of accuracy
(1) C, D             

(2) A, B, C, D               

(3) B, C, D             

(4) A, B, C

DNA replication in eukaryotes differs from replication in bacteria because:
(1) Synthesis of the new DNA strand is from 3' to 5' in eukaryotes and from 5' to 3' in bacteria

(2) Synthesis of the new DNA strand is from 5' to 3' in eukaryotes and from 3' to 5' in bacteria

(3) There are many replication forks in each eukaryotic chromosome and only one in bacterial DNA

(4) Synthesis of the new DNA strand is from 5' to 3' in eukaryotes and is random in prokaryotes
