内含子（intron）是真核生物细胞DNA中的间插序列。这些序列被转录在前体RNA中，经过剪接被去除，最终不存在于成熟RNA分子中。内含子和外显子的交替排列构成了 割裂基因 。在前体RNA中的内含子常被称作“间插序列”。

2014年5月8日 · • An exon is asequence of DNA that is expressed (transcribed) into RNA and then often, butwith many noteworthy exceptions[1] , translated into protein. Adjacent exons maybe separated by an intron , which is later removed from the RNAtranscript via …
What are Introns and Exons? - News-Medical.net
2023年7月22日 · Introns and exons are nucleotide sequences within a gene. Introns are removed by RNA splicing as RNA matures, meaning that they are not expressed in the final...
一叶知因丨基因科普之Intron ＆ Exon - 健康界
2021年4月29日 · 外显子和内含子都被转录到mRNA前体hnRNA中（heterogeneous nuclear RNA，不均一核RNA），当hnRNA进行剪接变为成熟的mRNA时，内含子被切除，而外显子保留。 实际上真正编码蛋白质的是外显子，而内含子则无编码功能，内含子存在于DNA中，在转录的过程中，DNA上的内含子也会被转录到前体RNA中，但前体RNA上的内含子会在RNA离开细胞核进行翻译前被切除。 外显子拼接形成成熟的mRNA，多数基因都有UTR（Untranslated Region，非 …

「先起源」(intron-early) 觀點 早期內含子可以子午催化、自我複製，是原始遺傳系統中不可缺失的一部分。現代內含子重新組合進基因組中後擁有了更大的進化潛力。
Intron - Wikipedia
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 intragenic region, i.e., a region inside a gene. [1] The term intron refers to both the DNA sequence within a gene and the corresponding RNA sequence in RNA transcripts. [2]
Introns vs Exons- Definition, 12 Major Differences, Examples
2022年1月19日 · Introns are non-coding DNA sequences within a gene that are removed by RNA splicing during maturation of the RNA product. The term ‘intron’ represents the intragenic region which is present within a gene. The term ‘introns’ indicates both the DNA sequences within the gene and the corresponding sequence in RNA transcripts.
RNA Splicing | Learn Science at Scitable - Nature
One of the steps in this processing, called RNA splicing, involves the removal or "splicing out" of certain sequences referred to as intervening sequences, or introns. The final mRNA thus consists...
Intron definition, exon definition and back-splicing revisited
2019年9月23日 · In yeast, which typically contain short introns and long exons, intron definition seems to dominate. By contrast, in vertebrates, where introns are longer and exons are shorter, exon definition...
