Q24

u have 20% of cytocine in DNA so this will be transcripted to 20% guanine in mRNA
U have 20 % of cytocine in DNA so there would be 20 % guanine (its complimantory base pair) which will be transcripted to guanine (20% in mRNA)

u r left with :- 100-(20+20) = 60%

this 60% would includes both Ucracil and ADenine bot in equal proprtion  as they are complimentory base pai
so half of 60 % would be ucracil

60%/2 = 30%

Q30

i know that co2 concentration would shift X to Y but dont know how cn this be dne by increasing pH

Thanks for the answer. I understand the first one but for Q30 I think you answered a wrong question. I'm talking about the one with the atrio-ventricular and the semi-lunar valves..
