WebIntrons and exons are regions of DNA that make up a gene. Exons are the portions of the DNA that code for a protein, while introns are the non-coding regions of DNA that interrupt the coding sequence of a gene. During the process of transcription, the entire gene (including both exons and introns) is copied into a messenger RNA (mRNA) molecule. WebThey were found to be highly informative in phylogenetic reconstruction of congeneric species, where introns provide a higher proportion of parsimony informative sites in comparison with traditional phylogenetic markers such as ITS and matK. At higher phylogenetic distance, where only coding regions could be aligned, ...

WebIntrons need to be removed from initial transcripts in order to generate the final messenger RNA (mRNA), which can be translated into an amino acid sequence.
