What is the chemical component of genes?

Answer 1

Chemical Composition of gene

When Fedrisch Meischer discovered nucleic acids its importance in heredity was not established. Now it is an established fact that nucleic acid is principal component of chromosomes. There are two types of Nucleic acids. They are Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA). DNA is the Nucleic acid found in the structure of chromosome. DNA content of diploid somatic cell is definite. In haploid gametes DNA content is reduced to half. Thus, it is definitely concluded that genetic material or hereditary material is DNA. The function of DNA is to store genetic information, to transmit it and to make use of it. Proteins are polymers of amino acids. Similarly nucleic acids are polymers of nucleotides. The structure formed by union of many similar units is called a polymer. There are three constituents of each nucleotides: 1. pentose sugar 2 phosphoric acid as phosphate 3. Nitrogen base.

Deoxyribose is the pentose sugar in DNA. There are two types of nitrogen bases.

1.Purine such as Adenine (A) and Guanine (G)

2. Pyrimidines such as Thymine (T) and Cytosine (C)

Besides this a bigger molecule called nucleoside is formed when sugar molecules join with nitrogen base. A still bigger molecule called nucleotide is formed when Nucleoside unites with phosphate. A polynucleotide chain is formed when sugar and phosphate units of different nucleotides join with each other

Answer 2

Genes are segments of deoxyribonucleic acid (DNA) that encode for polypeptides. DNA is made up of nucleotides, each of which are composed of a nitrogenous base (aromatic purines or pyrimidines), a sugar ring (deoxyribose), and phosphate group(s).

Answer 3

no, Genes are working subunits of DNA. However, DNA is a vast chemical information database that carries the complete set of instructions for making all the proteins a cell will ever need. Each gene contains a particular set of instructions, usually coding for a particular protein.

Answer 4

• a sugar group: ribose or deoxyribose
• a carboxyl-acid group
• a phosphate group
• one of 4 base groups: with ribose (A, U, C, G), with deoxyribose (A, T, C, G)

This the monomer(s) used to make the ultra long chain polymers of RNA and DNA, called nucleic acids.

Answer 5

Molecules of DNA contain information, coded in the sequence of nucleotides, for protein synthesis. -Vander's Human Physiology 10th Edition

Answer 6

The chemical component of genes is the DNA. In animals, plants, and fungi, the genes are contained within the cell nucleus.
