Question

What is nucleotides? ??

Answer 1

Hi.

here is your answer.

$nucleotides \:$
● The nucleotides are named according to their nitrogen base . Thus a nucleotides containing Thymine nucleotides and so on,

●The term nucleoside refers to the combination of a Pentose sugar and a purine or pyrimidine base.

● It does not contain a phosphate group. A combination of nucleoside and phosphate is called nucleotide.

● In s nucleotides, nitrogen base is attached to 1st carbon of sugar molecules by glycosidic bond .

●The phosphate group is joined with 5th carbon of the sugar by sugar phosphate bond.

hope it helps you ☺

Answer 2

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 within 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.

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 metabolism at a fundamental, cellular level. They carry packets of chemical energy—in the form of the nucleoside triphosphates Adenosine triphosphate (ATP), Guanosine triphosphate (GTP), Cytidine triphosphate (CTP) and Uridine triphosphate (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 (cyclic guanosine monophosphate or cGMP and cyclic adenosine monophosphate or 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.
