Question 26

Explain the process of splicing of hn-RNA in a eukaryotic cell.

Answer

The primary transcript contain both the exons and introns are non-functional, Hence it is subjected to a process called splicing  where the ingtrons are removed and exons are joined in a defind order. hn-RNA undergoes aditional processing called a capping and a tailing.

hn-RNA undergoes a process where the introns are removed and exons are joined to form m-RNA (functional) by the process called splicing.
