Answer:
removal of introns, addition of 5' cap and 3' tail to mRNA.
Explanation:
The mRNA is processed before it leaves nucleus. The introns are removed and exons are remain in mRNA. This process is called splicing. The 5' end is attached with a cap and 3' is attached with a polyadenylated tail. Thus mRNA is processed with these process before it leaves the nucleus.
<span>Naturally occurring in both humans and bacteria and functions in DNA replication. The process of DNA Replication is extremely complex. Especially in humans, and needs specific molecules, like ligase, to be done. This molecule can be found in other species too.</span>
