Gene A gene is a locus (or region) of DNA which is made up of nucleotides and is the molecular unit of heredity. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes.

Gene - what is, definition and function Gene is a segment of coding DNA (DNA that instructs the structure and function of cells throughout the body) composed of a specific sequence of nucleotides. The gene is the basic unit of inheritance that directs every facet of the body’s appearance and functions. Genes align along chromosomes in pairs.

Gene Therefore, a broad, modern working definition of a gene is any discrete locus of heritable, genomic sequence which affect an organism's traits by being expressed as a functional product or by regulation of gene expression.

Contents: Allele vs Gene A gene is a stretch of DNA or RNA that determines a certain trait. Genes mutate and can take two or more alternative forms; an allele is one of these forms of a gene. For example, the gene for eye color has several variations (alleles) such as an allele for blue eye color or an allele for brown eyes. An allele is found at a fixed spot on a chromosome.

Contents: Allele vs Gene A gene is a stretch of DNA that codes for a polypeptide via an RNA chain. These coded chains lead to “traits” in an individual, such as eye color and blood type. A gene is the basic unit of heredity. An allele is a variation of a gene. Genes come in many different forms, or alleles, that lead to the encoding of different RNA chains and, therefore, different traits.

What is a gene? By the traditional definition, a gene is 'transcribed' into mRNA which is then 'translated' into a protein, which will produce the desired effect in an organism's cell. Some genes may contain instructions for the production of RNA that is not translated into a protein, such as tRNA, rRNA, miRNA and siRNA.

- Genes are small sections of DNA within the genome that code for proteins. They contain the instructions for our individual characteristics – like eye and hair colour.1  A gene is a small section of DNA that contains the instructions for a specific molecule, usually a protein.2  The purpose of genes is to store information. In humans, alleles of particular genes come in pairs, one on each chromosome (we have 23 pairs of chromosomes). 2  If the alleles of a particular gene are the same, the organism is described as homozygous for that gene. 3  If they are different the organism is described as heterozygous for that gene.

- The modern working definition of a gene is a portion (or sequence) of DNA that codes for a known cellular function or process (e.g. the function make melanin molecules). A single 'gene' is most similar to a single 'word' in the English language. The nucleotides (molecules) that make up genes can be seen as 'letters' in the English language. Nucleotides are named according to which of the four nitrogenous bases they contain. The four bases are cytosine, guanine, adenine, and thymine.

Gene A gene is a segment of DNA that encodes function. A chromosome consists of a long strand of DNA containing many genes. A human chromosome can have up to 500 million base pairs of DNA with thousands of genes.he total complement of genes in an organism or cell is known as its genome, which may be stored on one or more chromosomes. A chromosome consists of a single, very long DNA helix on which thousands of genes are encoded. The region of the chromosome at which a particular gene is located is called its locus.

mutation in biology, a sudden, random change in a genegene, the structural unit of inheritance in living organisms. A gene is, in essence, a segment of DNA that has a particular purpose, i.e., that codes for (contains the chemical information necessary for the creation of) a specific enzyme or other protein.
