A sequence of DNA that is a part of a gene. Exons may be separated by introns.
Segment of a eucaryotic gene that consists of DNA coding for a sequence of nucleotides in mRNA; an exon can encode amino acids in a protein. Usually adjacent to a noncoding DNA segment called an intron.
the coding regions of DNA in a gene
The portion of the DNA sequence in a gene that contains the codons that specify the sequence of amino acids in a polypeptide chain, as well as the beginning and end of the coding sequence.
a region of DNA that codes for synthesis of a protein
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.
A DNA segment of a gene, the transcript of which appears in the mature RNA molecule.
A sequence within a gene or primary RNA transcript that is retained following the splicing reaction and thus represented in the final mature RNA product. Exons usually, but not always, represent protein-coding sequences.
a section of a gene that codes for proteins. (see intron)
A portion of a DNA molecule, in eukaryotes, that codes for part of a polypeptide. (Contrast with intron.)
A DNA sequence that contains instructions for making a protein. In many genes the exons are separated by "intervening" segments of DNA, known as introns, which do not code for proteins; in due time, these introns are spliced out of mRNA before translation.
Each of the segments in a gene that are transcribed, and whose transcripts are spliced together to form the messenger RNA. In some cases, different proteins can be coded by the same gene by alternative splicing, that is, by different combinations of exons forming different messenger RNAs, and, therefore, being translated into different proteins.

A coding segment of a split gene that is separated from the rest of the gene by a non-coding intron DNA sequence.
Those portions of a genomic DNA sequence which WILL be represented in the final, mature mRNA. 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.
A segment of DNA within a gene that contains instructions for making a protein.

The proteincoding DNA sequence of a gene. Compare intron.
A sequence of genomic DNA which becomes part of a messenger RNA. In eukaryotes, most genes are composed of multiple exons, arranged on a chromosome in the order in which they appear in mRNA, but physically separated by intervening sequences, or introns. The entire gene, including both exons and introns, is transcribed into RNA, and the introns are then spliced out of the RNA molecule to produce the final messenger RNA.
sequence of a gene's DNA that transcribes into protein structures; "exons are interspersed with introns"
a portion of DNA code in primary mRNA transcript eventually expressed as result of polypeptide synthesis
a portion of the gene sequence that is transcribed and is found in the mature messenger RNA derived from the gene, but is not necessarily a part of the sequence that encodes the final gene product

Coding sequence of DNA present in mature messenger RNA Related Terms: coding region ; intron ; open reading frame
The segment of a gene which codes for a polypeptide. During splicing, the exons are separated from the gene's introns - non-coding regions between exons.
Region of a gene which is not excised during transcription forming part of the mature mRNA and therefore specifying part of the primary structure of the gene product.
exons are those portions of a gene which code for proteins.
A section of a gene that contains the instructions for making a protein.
The coding portions of genes which are interspersed by non-coding introns. Together, the exons constitute the template from which proteins are made.

Coding sequence of DNA present in mature messenger RNA. Most genes have multiple exons.
Segments of a eukaryotic gene (or of its primary transcript) that reaches the cytoplasm as part of a mature mRNA, rRNA, or tRNA molecule.
The region of a gene that codes for protein synthesis. Where more than one exon exists for a given gene exons are spliced together and represented in the final mRNA.

any segment of an interrupted gene that is present in the transcribed final mRNA.
In eukaryotic cells, the part of the gene that is transcribed into messenger RNA and encodes a protein. See also intron, splicing.
an extraneous segment of genetic material (DNA) that is not expressed as proteins.
A sequence of messenger RNA that is translated into an amino acid chain, three bases at a time, each triplet sequence coding for a single amino acid. Synonym: reading frame.
a gene segments that has instructions for making a protein, as opposed to introns, which don’t have these instructions.
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.

a region in the coding sequence of a gene that is translated into protein (vs. introns which are not).
The protein-coding DNA sequences of a gene (see Intron).
The coding sequences within the gene. Exons are separated by so called introns, these are removed while still in the nucleus during mRNA maturing (splicing). The remaining exon areas then constitute the functional mRNA for protein biosynthesis.

A region of a gene that codes for a protein.
a region of a gene that is present in the final functional transcript (mRNA) from that gene. Exons are interspersed with introns; together the exons constitute the mRNA (messenger RNA) and are translated into protein; an exon is a sequence of a gene's DNA that transcribes into protein structures (comes from shortening of "expressed on"); for a diagram, see http://ghs.gresham.k12.or.us/science/ps/sci/ibbio/chem/nucleic/chpt15/intron.htm.
