Q. Nucleic acids are composed of
Solution:
Solution:
The nucleic acids are made up of nucleotides with a ribose sugar, nitrogenous bases, and a phosphate group. Both Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are nucleic acids. They contain the four nitrogenous bases, adenine, thymine, cytosine, and thymine. Uracil is present in RNA in place of thymine. These nitrogenous bases form hydrogen bonds with a partner base forming complementary base pairs. Adenine pairs with thymine by forming two hydrogen bonds and cytosine pairs with guanine by forming three hydrogen bonds. A covalent bond called phosphodiester bond is formed between the 5'-phosphate group of one nucleotide (ribose sugar with a phosphate group) and the 3'-OH group of another. Some nucleic acids can act as enzymes and have catalytic activities, like ribozyme.
