Question

Give example of nitrogen base in DNA.

Answer 1

DNA:

1. DNA is a polynucleotide made up of deoxyribonucleotide units that are covalently bonded.
2. It stores hereditary information within a cell and transmits it from generation to generation.

Polynucleotide:

1. A polynucleotide is a molecule made up of nucleotide monomers that are linked together by covalent bonds.
2. A nucleotide is a molecule made up of a nitrogen-containing base, phosphate group, and sugar (deoxyribose in DNA; ribose in RNA).

Example of nitrogen base in DNA:

1. Adenine, guanine, thymine, or cytosine.
