Intron: Part of a gene that is initially transcribed into the primary RNA transcript but then removed from it when the exon sequences on either side of it are spliced together. Also called an intervening sequence.

intron

(= intervening sequence) A non-coding sequence of DNA within a gene (cf. exon), that is transcribed into hnRNA but is then removed by RNA splicing in the nucleus, leaving a mature mRNA that is then translated in the cytoplasm. Introns are poorly conserved and of variable length, but the regions at the ends are self-complementary, allowing a hairpin

Intron

An intron is any nucleotide sequence within a gene that is removed by RNA splicing to generate the final mature RNA product of a gene. The term intron refers to both the DNA sequence within a gene, and the corresponding sequence in RNA transcripts. Sequences that are joined together in the final mature RNA after RNA splicing are exons. Introns are

Intron

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.

intron

A portion of messenger RNA (mRNA), as transcribed from the DNA of a eukaryote, which is removed by enzymes before the mRNA matures and is transplanted into protein. The portions of mRNA that remain after the excision of the introns are known as exons.

intron

Type: Term Pronunciation: in′tron Definitions: 1. A portion of DNA that lies between two exons, is transcribed into RNA, but does not appear in that mRNA after maturation because the intron is removed and the exons spliced together, and so is not expressed (as protein) in protein synthesis. By customary usage, the term is extended to the corr
