introns
Synonyms
Examples
After the introns have been removed via splicing, the mature mRNA sequence is ready for translation (bottom).
Biological functions and evolution While introns do not encode protein products, they are integral to gene expression regulation.
Double-stranded break repair via non-homologous end joining was recently identified as a source of intron gain when researchers identified short direct repeats flanking 43% of gained introns in Daphnia.
Although most of the TEs were located on introns, the experiment showed the significant difference on gene expressions between the population in Africa and other parts of the world.
Although the biomolecular mechanisms are different, the principle is the same: parts of the protein, called inteins instead of introns, are removed.
Eukaryotic RNA molecules are not necessarily co-linear with their DNA template, as introns are excised.
