What are the three chemical components of a dna nucleotide?

Explanation:

Deoxyribonucleic acid (DNA) is made up of the four types of nitrogen bases   called nucleotides, named as, adenine (A), thymine (T), guanine (G) and cytosine (C)

Nucleotides consist of three chemical components:

1. Nitrogenous Base:  Categories into purines and pyrimidines.

2. Pentose Sugar:  In DNA, the sugar is 2'-deoxyribose.

3. Phosphate Group: In DNA, a single phosphate group is PO43-.

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.
