Question

What are nucleotides? draw the structure of nucleotides presents in dna and give their names?

Answer 1

Nucleotides are organic molecules that serve as the monomer units for forming the nucleic acid polymers deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are essential biomolecules in all life-forms on Earth. Nucleotides are the building blocks of nucleic acids; they are composed of three subunit molecules: a nitrogenous base, a five-carbon sugar (ribose or deoxyribose), and at least one phosphate group. They are also known as phosphate nucleotides.

A nucleoside is a nitrogenous base and a 5-carbon sugar. Thus a nucleoside plus a phosphate group yields a nucleotide.

Nucleotides also play a central role in life-form metabolism at the fundamental, cellular level. They carry packets of chemical energy—in the form of the nucleoside triphosphatesATP, GTP, CTP and UTP—throughout the cell to the many cellular functions that demand energy, which include synthesizing amino acids, proteins and cell membranes and parts; moving the cell and moving cell parts, both internally and intercellularly; dividing the cell, etc.[1] In addition, nucleotides participate in cell signaling (cGMP and cAMP), and are incorporated into important cofactors of enzymatic reactions (e.g. coenzyme A, FAD, FMN, NAD, and NADP+).

In experimental biochemistry, nucleotides can be radiolabeled with radionuclides to yield radionucleotides.

Answer 2

Hello Dear.

Here is the answer---

→→→→→→→→→

Nucleotide are organic molecules which are the building blocks of DNA

[Deoxyribose Nucleic Acids]and the RNA [Ribose Nucleic Acids].

Nucleotide are made up of three parts---

1) Phosphate Group

2) Pentose Sugar

3) Nitrogenous Bases.

Nucleotide are also known as Phosphate Nucleotide.

-

The Nitrogenous Bases in the Nucleotide are---

1) Adenine

2) Guanine

3) Thymine [ Only In DNA]

4) Cytosine

5) Uracil [only in RNA]

Nucleotide are found in the molecules of Adenosine Tri-phosphate(ATP) which is the main source of the energy for the cell. Nucleotide make different Molecules that functions to make life Process.
