  1. Intron - Wikipedia

    These complex architectures allow some group I and group II introns to be self-splicing, that is, the intron-containing RNA molecule can rearrange its own covalent structure so as to precisely …

  2. Introns- Definition, Structure, Functions, Classes, Splicing

    Aug 3, 2023 · Introns are thousands of base pairs long and have many different cryptic splice sites which have sequence recognition available.

  3. What Are Introns and What Is Their Function? - Biology Insights

    Aug 14, 2025 · Introns are the non-coding, intervening sequences interspersed within these exons. Think of a gene as a recipe in a cookbook. Exons are the precise, actionable steps and …

  4. Intron - National Human Genome Research Institute

    2 days ago · An intron is a region that resides within a gene but does not remain in the final mature mRNA molecule following transcription of that gene and does not code for amino acids …

  5. intron / introns | Learn Science at Scitable - Nature

    Introns are also referred to as intervening sequences. Introns are non-coding sections of an RNA transcript, or the DNA encoding it, which are spliced out, or removed, before the RNA …

  6. Intron - Definition, Function and Structure | Biology Dictionary

    Aug 6, 2017 · An intron is a stretch of DNA that begins and ends with a specific series of nucleotides. These sequences act as the boundary between introns and exons and are known …

  7. Definition of intron - NCI Dictionary of Genetics Terms - NCI

    intron (IN-tron) The sequence of DNA in between exons that is initially copied into RNA, but is cut out of the final, mature messenger RNA transcript. Introns do not code for amino acids that …

  8. Intron - an overview | ScienceDirect Topics

    An intron is defined as a genomically encoded sequence that is removed from RNA transcripts during the splicing process, which can occur either through self-splicing or via the …

  9. Intron | genetics | Britannica

    Molecular complexes called spliceosomes, which are composed of proteins and RNA, have RNA sequences that are complementary to the junction between introns and adjacent coding …

  10. Intron - Wikiwand

    An intron is any nucleotide sequence within a gene that is not expressed or operative in the final RNA product. The word intron is derived from the term intrage...
