Gene (Autism)

Originally defined as the physical unit of heredity, it is probably best defined as the unit of inheritance that occupies a specific locus on a chromosome, the existence of which can be confirmed by the occurrence of different allelic forms. Genes are formed from DNA, carried on the chromosomes and are responsible for the inherited characteristics that distinguish one individual from another. Each human individual has an estimated 100,000 separate genes.

Gene (Bioinformatics)

Classically, a unit of inheritance. In practice, a gene is a segment of DNA on a chromosome that encodes a protein and all the regulatory sequences (promoter) required to control expression of that protein.

Gene (Biology)

A hereditary unit that occupies a specific location on a chromosome, determines a particular characteristic in an organism by directing the formation of a specific protein and is capable of replicating itself at each cell division.

Gene (Biomediation)

A section of DNA coding for a single polypeptide chain, a particular species of transfer or ribosomal RNA, or a sequence that is recognized by and interacts with regulatory proteins.

Gene (Biotechnology)

The fundamental unit of heredity; a bundle of information for a specific biological structure or function.

Gene (Breast Cancer)

A unit of genetic material (DNA) that carries the directions a cell uses to perform a specific function.

Gene (Cancer)

An organised sequence of bases on a chromosome that "spells out" the information necessary to construct a specific protein using the genetic code. Every cell contains thousands of genes that act as blueprints to produce proteins that are essential to the cell's function.

Gene (Developmental Psychology)

Any of the units occurring at specific points on the chromosomes, by which hereditary characters are transmitted and determined: Each is regarded as a particular state of organization of the chromatin in the chromosome, consisting primarily of DNA and protein.

Gene (Diabetes)

A basic unit of heredity. Genes are made of DNA, a substance that tells cells what to do and when to do it. The information in the genes is passed from parent to child-for example, a gene might tell some cells to make the hair red or the eyes brown.

Gene (Food)

A natural unit of the hereditary material, which is the physical basis for the transmission of the characteristics of living organisms from one generation to another. e basic genetic material is fundamentally the same in all living organisms; it consists of chain-like molecules of nucleic acids—deoxyribonucleic acid (DNA) in most organisms and ribonucleic acid (RNA) in certain viruses—and is usually associated in a linear arrangement that (in part) constitutes a chromosome.

Gene (Food and Health)

A natural unit of the hereditary material, which is the physical basis for the transmission of the characteristics of living organisms from one generation to another. The basic genetic material is fundamentally the same in all living organisms; it consists of chain-like molecules of nucleic acids—deoxyribonucleic acid (DNA) in most organisms and ribonucleic acid (RNA) in certain viruses—and is usually associated in a linear arrangement that (in part) constitutes a chromosome.

Gene (Fossils)

A sequence of nucleotides coding for a protein (or, in some cases, part of a protein); a unit of heredity.

Gene (Gaucher Disease)

A piece of DNA that occupies a specific location on a chromosome and which defines a person's makeup and function.

Gene (Gene Testing)

A unit of inheritance; a working subunit of DNA. Each of the body's 20,000 to 25,000 genes contains the code for a specific product, typically, a protein such as an enzyme. (Revised: October 2004)

Gene (Genetics)

A single trait that is passed from generation to generation. A gene corresponds to the biological information that describes a single protein. This information is coded in the string of nucleotide bases, A,C,T and G.

Gene (Genetics and Food)

A discrete unit of hereditary information. Contained within DNA (which coils together to form chromosomes) found inside the nucleus of a living thing's cells. A given gene is made up of a distinct sequence of nucleotides — and it is this genetic 'code' that defines particular characteristics of a living organism.

Gene (Genetics and Genealogy)

The fundamental functional and physical unit of heredity passed from parent to offspring. Genes are the life function information bearing segments of DNA. Most genes contain the information for making a specific protein. Genes are sequences of DNA information containing several hundred to a few thousand DNA nucleotide instruction data points. Each gene performs a fundamental and specific function such as providing the information to make a protein. Genes control heredity and control day-to-day functions of cells and control the manufacture of proteins. The human genome has about 25,000 separate genes. See Genetic Code.

Gene (Genome)

The fundamental physical and functional unit of heredity. A gene is an ordered sequence of nucleotides located in a particular position on a particular chromosome that encodes a specific functional product (i.e., a protein or RNA molecule).

Gene (Gerontology)

1. A functional unit of heredity. It is a segment of DNA located at a specific site on a chromosome whose length is typically several thousand base pairs. A gene directs the formation of an enzyme or other protein by means of transcription and translation.
2. A sequence of DNA that can be activated and copied into messenger RNA or mRNA (by a process known as transcription). mRNA is processed and then translated by ribosomes into a sequence of amino acids, which are joined together by peptide bonds to form a protein at cell organelles called endoplasmic reticulum Each triplet of bases (or codon) in mRNA specifies a different amino acid (out of 20 possible choices). It's this sequence of amino acids that determines the identity of a protein (its primary structure). The folding pattern (secondary, tertiary, and quartinary structure) of the primary sequence determines its three-dimensional morphology and ultimately its function (e.g., a structural vs. an enzymic function).

Gene (HIV and AIDs)

A sequence of DEOXYRIBONUCLEIC ACID (DNA) in the CHROMOSOMES that determines the structure of a specific PROTEIN or ENZYME. Genes regulate the METABOLISM of individual cells and the development and specialization of body cells and tissues.

Gene (Hamster)

A hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines an individual characteristic in an organism. Genes undergo mutation if their DNA sequence changes.

The basic unit of DNA, which is responsible for passing genetic information; each gene contains the instructions for the production of a certain protein

Gene (Microbiology)

The fundamental physical and functional unit of heredity (Usually DNA, Some organisms have RNA a gene). A gene is an ordered sequence of nucleotides located in a particular position on a particular chromosome that encodes a specific functional product (i.e., a protein or RNA molecule) that contributes to or influences the phenotype of the cell. A gene usually contains coding regions, introns, untranslated regions and control regions. See gene expression.

Gene (Pests)

A biochemical unit of hereditary, often coding for an entire protein.

Gene (Pompe Disease)

The functional and physical unit of heredity that occupies a specific location (locus) on a chromosome. Formed from DNA, genes are passed from parent to offspring and are responsible for the inherited characteristics that distinguish one individual from another.

Gene (Prader-Willi Syndrome)

A unit of genetic information. Usually contains the genetic code for one protein.

Gene (Science)

A functional hereditary unit that occupies a fixed location on a chromosome, has a specific influence on phenotype, and is capable of mutation to various allelic forms

Gene (Yeast Genome)

The definition of a gene changes as more properties are revealed. Two classes are generally recognized: (1) genes that are transcribed into mRNAs, which enter ribosomes and are translated into polypeptide chains, and (2) genes whose transcripts are used directly (tRNAs, rRNAs, snRNAs, etc.). Class I genes are also known as structural genes, and have been referred to as cistrons in earlier literature. There are also other shorter DNA segments that are not transcribed but instead serve as recognition sites for enzymes and other proteins that function during replication or transcription. These types of elements are generally referred to as regulatory sequences, and should not be confused with regulatory genes, which encode proteins that bind to regulatory sequences.
