A noncoding DNA sequence within a gene that is initially transcribed into messenger RNA but is later snipped out See Coding, DNA, Messenger RNA, Transcription
The non-coding (intervening) sequence of a gene that is transcribed into RNA but then excised by splicing to produce an mRNA transcript Recently eukaryotic nuclear introns have been found to encode proteins
The DNA base sequences interrupting the protein-coding sequences of a gene on genomic DNA; these sequences are transcribed into RNA but are cut out of the messager RNA (mRNA) before it is translated into a protein molecule
DNA sequences that interrupt the protein-coding sequence of a gene; introns are transcribed into mRNA but the sequences are eliminated from the RNA before it is used to make protein
A length of DNA which is interspersed among the protein-coding sequences (exons) in a gene Introns are transcribed (see transcription) into mRNA but are then cut out of the mRNA sequence before protein synthesis occurs Source : PhRMA Genomics
In eukaryotes, bases of a gene transcribed but later excised from the mRNA prior to exporting from the nucleus and subsequent translation of the message into a polypeptide
a non-coding sequence separating coding sequences which is removed after transcription to RNA and therefore does not encode a polypeptide (protein) See also intervening sequence
DNA sequence that interrupts the protein-coding sequence of a gene; an intron is transcribed into RNA but is cut out of the message before it is translated into protein See also: exon
A segment of DNA that is transcribed into mRNA but is then cut off from the RNA, leaving behind the exon sequences to be translated into polypeptides Back to Homepage J j Back to Homepage K k Back to Homepage L l
A nucleotide sequence in eukaryotes that must be excised from a structural gene transcript in order to convert the transcript into a mature messenger RNA molecule containing only coding sequences that can be translated into the amino acid sequence of a polypeptide
'Intervening sequence' A nucleotide sequence in a gene that does not code for the gene product Introns, which are only found in eukaryotes, are transcribed into messenger RNA but are subsequently removed from the transcript before translation Their functional significance is controversial
