All DNA nucleotides contain the same deoxyribose and phosphate group, but different bases.
<h3>What is a DNA molecule?</h3>
DNA is a biological polymer of deoxyribonucleic acid that has four different chemical groups, called bases: adenine, guanine, cytosine, and thymine.
The DNA molecule is made up of monomers called nucleotides, which is made up of the following:
- Phosphate group
- Nucleotide bases
- Five carbon sugar
The five carbon sugar and phosphate group of a DNA molecule are the same but they possess different nucleotide bases.
