Question

What are the three chemical components of a dna nucleotide?

Answer 1

Answer:

These are the three chemical components of nucleotide:

i) Nitrogenous Base, ii) pentose sugar and iii) phosphate group.

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-.

Answer 2

The three chemical components of a DNA nucleotide -

a nitrogenous base, a five-carbon sugar (ribose or deoxyribose), and at least one phosphate group.

DNA

• is an essential biomolecule within all life-form on Earth.
• Nucleotides are the building blocks of nucleic acids.
• Nucleotides are organic molecules that serve as the monomer units for the formation of nucleic acid polymers deoxyribonucleic acid (DNA)
• They are composed of three subunit molecules:

1. Nitrogenous base - Purines or pyrimidines such as Adenine, Guanine, Cytosine, Thymine
2. a five-carbon sugar (ribose or deoxyribose) - deoxyribose sugar
3. Phosphate group - 1 phosphorus atom joined to 4 oxygen atoms
