Adenine can undergo a spontaneous change to hypoxanthine

Adenine can undergo a spontaneous change to hypoxanthine in a cell, leading toa DNA base pair mismatch. The CORRECT combination of enzymes that areinvolved in repairing this damage is(A) Nuclease, DNA polymerase, DNA ligase(B) Nuclease, DNA ligase, helicase(C) Primase, DNA polymerase, DNA ligase(D) Primase, helicase, DNA polymeraseQ.47 Consider the ordinary differential equation 2 2( , ) 2dy f x y x ydx    .If (1) 1y  , the value(s) of (1.5)y , using the Euler’s implicit method[𝑦௡ାଵ = 𝑦௡ + ℎ𝑓(𝑥௡ାଵ, 𝑦௡ାଵ)] with a step size of h = 0.5, is (are)(A) −1 − 5√0.3(B) −1 + 5√0.3(C) 1 + 5√0.3(D) 1 − 5√0.3
