Definition Of Gene Family

A group of genes related in structure and often in function.

Definition of gene family. A gene family is a set of several similar genes formed by duplication of a single original gene and generally with similar biochemical functions one such family are the genes for human hemoglobin subunits. For example the hemoglobin genes belong to one gene family that was created by gene duplication and divergence. 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. Gene families a set of gene s with a known homology and are in general biochemically similar.

The presence of related genes in other species the degree of conservation of sequence or domain structure among the family members and the dispersion of the family on the chromosomes. These two gene clusters are thought to have arisen as a result of a precursor gene. What does gene family mean. The genes belonging to a gene family are descended from an ancestral gene.

Meaning of gene family. What does gene family mean. The genes in a gene family are descended from an ancestral gene. A group of genes that are related in structure and often in function.

The ten genes are in two clusters on different chromosomes called the α globin and β globin loci. Gene family a group of genes whose exons are related having been derived from an ancestral gene. For example the hemoglobin genes belong to one gene family that was created by gene duplication and divergence. For example the hemoglobin genes of critical importance to red blood cells belong to one gene family created by gene duplication making extra copies of a gene and divergence divergent changes in the copies of the gene.

The genes in a gene family are descended from an ancestral gene. Information about gene family in the titi tudorancea encyclopedia. Gene family definition noun plural. Supplement gene s are categorized into families based on shared nucleotide or protein sequences.

Meaning of gene family. Proper usage and sense of the word phrase gene family. A group of genes that are related in structure and often in function. Gene definition the basic physical unit of heredity.
