1.	What are the various types of nitrogen bases found in DNA ? Name the type of bond seen between (i) two nitrogen bases of DNA (ii) phosphate and hydroxyl group of sugar of DNA.
Answer» Types of nitrogenous bases found in DNA are: (a) Adenine : Abbreviated 'A', has a 2-ring structure, so that it is a purine. (b) Thymine: Abbreviated T, is a pyrimidine, which. means it has a 1-ring structure. It's only present in DNA, where it pairs with adenine. (c) Guanine: Abbreviated 'G', is part of both DNA, where it bonds with cytosine. (d) Cytosine : abbreviated C, is part of DNA and bonds with guanine. It has one ring, so it's a pyrimidine. (i) Hydrogen bond (ii) Phosphodiester bond

Answer»

Types of nitrogenous bases found in DNA are:

(a) Adenine : Abbreviated 'A', has a 2-ring structure, so that it is a purine.

(b) Thymine: Abbreviated T, is a pyrimidine, which. means it has a 1-ring structure. It's only present in DNA, where it pairs with adenine.

(c) Guanine: Abbreviated 'G', is part of both DNA, where it bonds with cytosine.

(d) Cytosine : abbreviated C, is part of DNA and bonds with guanine. It has one ring, so it's a pyrimidine.

(i) Hydrogen bond

(ii) Phosphodiester bond
