In which phase does mismatch repair occurs to correct replication errors?

a) M
b) G 1
c) G 0
d) S
e) G 2




  #2

S PHASE.

NOT SURE


  #3

It should be B, S is for synthesis of DNA.


  #4

THANX FOR CORRECT ME. grin


  #5

I am not sure about the answer.


  #6

i think G2


  #7

G1 grow
S synthesiof DNA
G2 Grow
G0 quiescent G1 phase


  #8

yes mash is correct: answer is G2

most DNA repair occur in G1 but mismatch repair occur in G2


  #9

yes in G2


  #10

mousa, how did u find such an old post..


  #11

G2


  #12

old post good q

its G2!


  #13

100% G2



  #14

Mismatch repair occurs G2 phase

mlh1 and msh2 are the mismatch repair genes. defects lead to HNPCC ( lynch syndrome)



  #15

I truly have no idea what os the answer.
I hate step1


  #16

Ans - G2,

because mismatch of base pairs occurs during replication (S phase)

this escapes the proofreading function of DNA polymerase.

After S phase, its in G2 phase that mismatch repair enzymes slide over the replicated DNA to scan for mismatch base pairs.
