Question

A mismatch occurs at the position indicated. Correctly repair this DNA. [1] CH, 5' - GATCTCAGG - 3' 3' - CTAGAGGCC - 5'

Answer 1

in the above DNA, there is a mismmatch shown where A is basepaired with G

which is wrong

because A always pair with T and vice versa in DNA (double bond) (U in RNA)

while C pairs with G and vice versa (triple bond)

Hence the lagging strand 3' to 5' will show T instead of G

hence,

5' GATCTCAGG 3'

3' CTAGAGGCC 5'

I hope i was able to help you with the answer ! :)
