DNA vs RNA

Q.

Why is RNA called an acid?

Q. The base that is not found in DNA but found in RNA is

1. Thymine
2. Uracil
3. Adenine
4. Guanine

Q. Match the following, considering nucleic acids:

$\begin{array}{cc}Column-I& Column-II\\ p.SugarinDNA& i.Adenine,Guanine\\ q.Purines& ii.Ribose\\ r.SugarinRNA& iii.Deoxyribose\\ s.Pyrimidines& iv.Cytosine,Thymine,Uracil\end{array}$

1. p-ii, q-i, r-iii, s-iv
2. p-iv, q-ii, r-iii, s-i
3. p-iii, q-iv, r-ii, s-i
4. p-iii, q-i, r-ii, s-iv

Q. DNA differs from RNA in

1. Nature of sugar alone
2. Nature of purines alone
3. Nature of sugar and pyrimidines
4. All the above

Q. Which of the following is/are similarities between DNA and RNA?

1. It is chemically and structurally stable.
2. It provides scope for mutations leading to evolution.
3. It can replicate.
4. All of the above.

Q. What makes RNA mutate faster than DNA?

1. The presence of uracil in place of thymine
2. Single-stranded structure
3. The 2’-OH group
4. None of these

Q. Thymine is stabler than uracil.

1. True
2. False
