Exon - Wikipedia
网页An exon is any part of a gene that will form a part of the final mature RNA produced by that gene after introns have been removed by RNA splicing. The term exon refers to both the DNA sequence within a gene and to the corresponding sequence in RNA transcripts.
Exon - Definition, Structure and Function | Biology Dictionary
网页2017年8月6日 · An exon is a coding region of a gene that contains the information required to encode a protein. In eukaryotes, genes are made up of coding exons interspersed with non-coding introns. These introns are then removed to make a functioning messenger RNA (mRNA) that can be translated into a protein.
外显子 - 维基百科，自由的百科全书
网页外显子 （英語： Exon）是 真核生物 基因 的一部分，它在 剪接 后仍会被保存下来，并可在 蛋白质生物合成 过程中被 表达 为 蛋白质。 而 内含子 则会在剪接过程中被除去。 所有的外显子一同组成了遗传信息，该信息会体现在 蛋白质 上。 剪接方式并不是唯一的（参看 替代剪接），所以外显子只能在成体mRNA中被看出。 即使是使用 生物信息学 方法，要精确预测外显子的位置也是非常困难的。 真核生物的基因，其线性表达被内含子阻断，这就是所谓 …

网页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 the splicing mechanism. (From Wikipedia) •UTR（UntranslatedRegions)即非翻译区，是信使RNA（mRNA）分子两端的非编码片段。
Exon - National Human Genome Research Institute
网页2024年9月12日 · An exon is a region of the genome that ends up within an mRNA molecule. Some exons are coding, in that they contain information for making a protein, whereas others are non-coding. Genes in the genome consist of exons and introns.
What are Introns and Exons? - News-Medical.net
网页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 messenger RNA (mRNA) product, while...
Exons And Introns: Functions and Types - Microbe Online
网页Exons are regions of a gene that contain coding information for the synthesis of proteins. During the process of gene expression exons are transcribed into mRNA and eventually translated into proteins. Exons are interspersed with introns. Introns are non-coding regions of a gene that interrupt the coding sequences, or exons, within the gene.
exon / exons | Learn Science at Scitable - Nature
网页Exons are coding sections of an RNA transcript, or the DNA encoding it, that are translated into protein. Exons can be separated by intervening sections of DNA that do not code for proteins,...
Exon Definition and Examples - Biology Online Dictionary
网页2022年6月16日 · Biology definition: When describing from the ‘DNA point of view’, exons are those parts of a gene that eventually get incorporated in the final structure of a mature RNA post-splicing.
What Are Exons? — Definition & Role in Transcription - expii
网页Exons are the regions of RNA that are used to produce amino acids and proteins. A gene on DNA contains more base pairs than necessary to produce the desired protein. These extra base pairs have to be removed so that the protein can function properly.
