1 In eukaryotes which DNA polymerase is primarily responsibl

1. In eukaryotes, which DNA polymerase is primarily responsible for filling in the gaps in the DNA generated during base excision repair?  

DNA polymerase

DNA polymerase

DNA polymerase

DNA polymerase ö

DNA polymerase

2. High energy electromagnetic radiation includes which of the following?  

ultraviolet light

x-rays

gamma rays

two of the above

all three of the above

3. Which of the following types of damage to DNA cannot be caused by x-rays and gamma rays?  

deletions

duplications

insertions

translocations

inversions

4. Error-prone DNA polymerases catalyze __________ DNA synthesis.  

translesion

transtrand

single-stranded

double-stranded

none of the above

5. Synthesis of which of the following proteins is not induced by the SOS signal?  

DNA polymerase I

DNA polymerase II

DNA polymerase IV

DNA polymerase V

none of the above

6. N-glycosyl bond cleavage is the first step of:  

Base excision repair

Mismatch repair

Nucleotide excision repair

SOS response

photoreactivation

Solution

1.DNA polymerase is used to fill in the gaps

2.two of the above as x rays and gamma rays are electromagnetic radiations not UV rays

3.Transloctions as both of them cannot do this.

4.double-stranded DNA synthesis as it converts a dna with 2 strands into one.
