Definition of intron - NCI Dictionary of Genetics Terms
Listen to pronunciation. (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 protein encoded by the gene.

Group III intron
Group III intron is a class of introns found in mRNA genes of chloroplasts in euglenid protists. Splicing is done with two transesterification reactions with a dVI bulged adenosine as initiating nucleophile; the intron is excised as a lariat.

Are introns conserved among cells? To elaborate on the title: Among somatic, post-mitotic cells, would the same intron on a given chromosome have the same sequence among all cells descended from a progenitor cell?
Any given genomic locus (intron, exon, intergenic region) _probably_ doesn't mutate most of the time.

Small t intron
The small T intron is an intron, that is used in some plasmid vectors, in order to induce gene expression in mammalian cells. Function
The function of this intron in the vectors is unknown, but it is theorized that it might be involved in splicing or translation efficiency.

What are limiting factors for intron length? For predicting genes from a sequenced genome, you need to set a maximum intron length. How long can introns get in animals? Is there some limit?
. < shows that most introns are less than about 10 kb (and personal experience in Drosophila confirms that - I've _rarely_ seen an intron bigger than about since it's nearly impossible to detect the splicing reaction, particularly if they're very large, it's not clear whether they are spliced as one BIG intron
