Q. DNA and RNA differ by

Molecular Basis of Inheritance

Solution:

• A nucleotide has three components-a nitrogenous base, a pentose sugar (ribose in case of RNA, and deoxyribose for DNA), and a phosphate group
• There are two types of nitrogenous bases-Purines (Adenine and Guanine), and Pyrimidines (Cytosine, Uracil and Thymine)
• Cytosine is common for both DNA and RNA and Thymine is present in DNA
• Uracil is present in RNA at the place of Thymine
