Solution
- DNA:
- It is the genetic material of the majority of the organisms.
- It is double-stranded.
- Deoxyribose sugar is present.
- Nitrogen bases like Adenine, Guanine, Cytosine, Thymine are present.
- Specific base pairing is observed.
- Total number of purines is equal to the total number of pyrimidine. Thus, the purine to pyrimidine ratio is 1:1.
- It is present in the nucleus.
- It is responsible for determining hereditary characters and for formation of RNA.
- RNA:
- It is a genetic material only of some viruses.
- It is single-stranded.
- Ribose sugar is present.
- Nitrogen bases like Adenine, Guanine, Cytosine, Uracil are present.
