Hydrolysis of which of the following nucleic acids does not give equal number of $A$ and $T$ or G and C. Figure

  • Correct answer
    A
    (A), (B), (C)
  • B
    $(B),(C),(D)$
  • C
    (B) only
  • D
    (A) only

Solution

Hydrolysis of $m$-RNA, single strand DNA and $r$-RNA does not give equal number of $A$ and $T$ or $G$ and C. This is because $a, b$ and $c$ are single strand whereas (d) i.e. double helix DNA is double strands. Thus, (d) will give equal number of $\mathrm{A}$ and T or G and C.

Hence, the correct answer is option: 'A'.
