Definition Of Gene With Reference

They are composed of deoxyribonucleic acid dna except in some viruses which have genes consisting of a closely related compound called ribonucleic acid rna.

Gene definition the basic physical unit of heredity. Gene definition is a specific sequence of nucleotides in dna or rna that is located usually on a chromosome and that is the functional unit of inheritance controlling the transmission and expression of one or more traits by specifying the structure of a particular polypeptide and especially a protein or controlling the function of other genetic material. A gene is an extremely specific sequence of nucleotide monomers that has the ability to completely or partially control the expression of one or more traits in every type of living organism. The genotypes together with the other factors e g.

References and further reading a gene is the fundamental physical and functional unit of heredity. A linear sequence of nucleotides along a segment of dna that provides the coded instructions for synthesis of rna which when translated into protein leads to the expression of hereditary character. Genes are formed from deoxyribonucleic acid dna and in the case of some viruses ribonucleic acid rna polymers.
