  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 remove …

  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 Is an Intron and Its Role in Gene Expression?

    Aug 19, 2025 · An intron is a nucleotide sequence located within a gene that is ultimately not present in the final, mature RNA product. Its counterpart, the exon, represents the portions of the gene that are …

  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 that make up …

  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 molecule is...

  6. Intron - Definition, Structure, Functions - Biology Notes Online

    May 30, 2024 · A DNA segment that begins and ends with a particular sequence of nucleotides called an intron. As the boundary between introns and exons, these sequences are known as splice sites.

  7. 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 spliceosome, an RNA …

  8. 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 regions …

  9. Intron - (General Biology I) - Vocab, Definition, Explanations | Fiveable

    An intron is a non-coding segment of a gene that is transcribed into RNA but is removed during the process of RNA splicing before translation into a protein.

  10. 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 make up the …
