For Exon we have terms and definitions in 10 topics. The topics are Bioinformatics, Evolution, Fossils, Genetics, Genome, Health Informatics, Huntingtons Disease, Immunization, Microbiology and Yeast Genome.

Exon (Bioinformatics)

The region of DNA within a gene that codes for a polypeptide chain or domain. Typically a mature protein is composed of several domains coded by different exons within a single gene.

Exon (Evolution)

The nucleotide sequences of some genes consist of parts that code for amino acids, with other parts that do not code for amino acids interspersed among them. The coding parts, which are translated, are called exons; the interspersed non-coding parts are called introns.

Exon (Fossils)

The nucleotide sequences of some genes consist of parts that code for amino acids, with other parts that do not code for amino acids interspersed among them. The coding parts, which are translated, are called exons; the interspersed non-coding parts are called introns.

Exon (Genetics)

The part of a gene that contains the code for producing the gene's protein. In humans, exons are often separated by long regions of DNA called introns, or "junk DNA," that have no apparent function.

Exon (Genome)

The protein-coding DNA sequence of a gene.
See also: intron

Exon (Health Informatics)

Th protein-codin DN sequence o gen (se Intron).

Exon (Huntingtons Disease)

A stretch of DNA that codes for part of a protein.

Exon (Immunization)

The region of DNA coding for a protein or a segment of a protein.

Exon (Microbiology)

Those portions of a genomic DNA sequence which will be represented in the final, mature mRNA ie. A contiguous segment of genomic DNA that codes for a polypeptide in a gene.The term "exon" can also be used for the equivalent segments in the final RNA. Exons may include coding sequences, the 5' untranslated region or the 3' untranslated region.

Exon (Yeast Genome)

A portion of a split gene that is included in the transcript of a gene and survives processing of the RNA to become part of the spliced messenger of a structural RNA. Exons generally occupy three distinct regions of genes that encode proteins. Exons in the first region are not translated into protein, but signal the beginning of RNA transcription and contain sequences that direct the mRNA to ribosomes for protein synthesis. Exons in the second region contain the information that is translated into the amino acid sequence of the protein, and are sometimes referred to as coding exons. Exons in the third region are transcribed into the part of the mRNA that contains the signals for the termination of translation and for the addition of a polyadenylate tail.
