Thermo-stability in DNA is contributed mostly by:: (A) A=T, (B) GEC, (C) Molecular base, (D) Parallel arrangement
Answer is B. B i.e. G CThermostability in DNA is constributed mostly by C GQ because there are 3 Hydrogen bonds between C & GQ. G C bonds are much more resistant to denaturation or melting than A= T rich region (2 Hydrogen bonds)
