Answer 1

The comparison is as follows-

1. Number of strands : DNA - 2, RNA - 1

2. Location in the cell : DNA - nucleus, RNA - cytoplasm

3. Type of sugar : DNA - Deoxyribose, RNA - Ribose.

4. Nitrogenous basepair : DNA - Adenine with Thymine and Guanine with Cytosine, RNA - Adenine with Uracil and Guanine with Cytosine.

Q1. What are the components of the DNA and RNA molecule?

DNA contains nitrogenous base namely Adenine, Thymine, Cytosine and Guanine, deoxyribose sugar and phosphate.

RNA contains nitrogenous base namely Adenine, Uracil, Cytosine and Guanine, ribose sugar and phosphate.

Q2. What is the structural difference between DNA and RNA?

DNA is two stranded and RNA has one strand.

Q3. What nitrogenous base is found in RNA but not in DNA?

Uracil is the nitrogenous base found in RNA but not in DNA.
