Definitions related to introns:
-
Noncoding intervening sequence in a gene; separates the coding sequences.CRISP ThesaurusNational Institutes of Health, 2006
-
Non-coding, intervening sequences of DNA that are transcribed, but are removed from within the primary gene transcript and rapidly degraded during maturation of messenger RNA.NCI ThesaurusU.S. National Cancer Institute, 2021
-
The sequence of DNA in between exons that is initially copied into RNA but is cut out of the final RNA transcript and therefore does not change the amino acid code. Some intronic sequences are known to affect gene expression.NCI Dictionary of Cancer TermsU.S. National Cancer Institute, 2021
-
Sequences of DNA in the genes that are located between the EXONS. They are transcribed along with the exons but are removed from the primary gene transcript by RNA SPLICING to leave mature RNA. Some introns code for separate genes.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
