Human genes that encode proteins often contain non-coding segments known as introns. Removing introns is crucial for the proper expression of genetic information. Understanding how our cells ...
Shown is the splicing pathway. The pre-messenger RNA (pre-mRNA) has exons (blue) and introns (pink). The spliceosome (not shown) was known to catalyze two chemical reactions (black arrows) in a ...
Although the participation of spliceosomes is almost always required for intron removal, a few types of genes have self-splicing RNA introns.
