Statement A : Adenine cannot pair with cytosine. Statement B : Because there would be two hydrogen atoms in one of the bonding positions and none at the other.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Adenine (purine)cannot pair with cytosine (pyrimidine) because purines do not pair with purines and pyrimidines do not pair with pyrimidines. And pyrimidines are much farther from each other and they need to come closer enough for the hydrogen bonds to be formed between them.

Total amount \(\mathrm{A}\) and \(\mathrm{T}\) in DNA is \(45 \%\) Amount of guanine will be ..
1 \(22.5 \%\)
2 \(27.5 \%\)
3 \(35 \%\)
4 \(55 \%\)
Explanation:
\(\mathrm{A}+\mathrm{T}+\mathrm{G}+\mathrm{C}=100 \%\) Since \(\mathrm{A}+\mathrm{T}=45 \%\) \(45 \%+\mathrm{G}+\mathrm{C}=100 \%\) \(\mathrm{G}+\mathrm{C}=100 \%-45 \%\) \(\mathrm{G}+\mathrm{C}=55 \%\) \(\mathrm{G} / \mathrm{C}=55 \backslash 2\) \(\mathrm{G}=27.5 \%\) hence ans is \(27.5 \%\)
