What is Gene

Sentence in the genetic alphabet codifying a cell instruction.

Essential component of the genetic information. The multiple combinations lead to individual differentiations of the organisms.

Gene has different definitions depending on the way it is studied in biology. As per classical (Mendelian) genetics a gene is the basic physical and functional unit of heredity. According to molecular biology a gene is a locus (or region) of DNA which is made up of nucleotides and is the molecular unit of heredity.

A hereditary factor; functionally indivisible unit of genetic material; section of the DNA molecule encoding the primary structure of the polypeptide.

Basic information unit in a chromosome.

The basic unit of heredity. Typically, a gene is a segment of DNA that occupies a particular location on a chromosome, and encodes for a protein.

The fundamental hereditary unit of living organisms. Genes correspond to portions of the genetic code localized in specific positions within the sequence (DNA or, more rarely, RNA) and contain all the information necessary for the production of a protein. They are contained and organized within chromosomes, present in all cells of an organism.

It is a portion of DNA molecule which serves as the basic unit of heredity.

Each of the rules which codifies one action of the cell.

1. A unit of DNA that carries information for the biosynthesis of a specific product in the cell. 2. Ultimate unit by which inheritable characteristics are transmitted to succeeding generations in all living organisms. Genes are contained by, and arranged along the length of, the chromosome. The gene is composed of deoxyribonucleic acid (DNA). Each chromosome of a species has a definite number and arrangement of genes, which govern both the structure and metabolic functions of the cells and thus of the entire organism. Genes provide information for the synthesis of enzymes and other proteins and specify when these substances are to be made. Alteration of either gene number or arrangement can result in mutation (a change in the inheritable traits).http://www.amfar.org/cgi-bin/iowa/bridge.html?page=G

A hereditary unit consisting of a sequence of DNA that contains all information necessary to produce a molecule that performs some biological function.

The gene is the fundamental hereditary unit of living organisms. Genes correspond to portions of the genetic code localized in specific positions within the sequence (DNA or, more rarely, RNA) and contain all the information necessary for the production of a protein. They are contained and organized within chromosomes, present in all cells of an organism.

A hereditary factor; functionally indivisible unit of genetic material; section of the DNA molecule encoding the primary structure of the polypeptide.

Each of the rules which codifies one action of the cell.

In a living organism a gene is a unit of heredity at the molecular level. It is transferred from the parent to the offspring and determines the characteristics of the offspring.

Any cell in the chromosome.
