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 ...
Although the participation of spliceosomes is almost always required for intron removal, a few types of genes have self-splicing RNA introns.
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 ...
