What is spilicing and where does it occur exactly correct answer

is a form of RNA processing in which newly made precuesor messanger

splicing takes place within the nucleus

Splicing occurs in the nucleus of a cell. DNA contains regions called introns and exon.

The Introns have to be removed because if they weren't they would be translated into non-functioning proteins. A process called RNA splicing removes these introns and splices exons together.

snRNAs form an RNA protein complex called a spliceosome that cuts the pre-mrna and releases the introns and joins the ends of the exons together to produce mature mRNA.

Alternative splicing is a process for generating different mature mRNA from a single gene by splicing together different sets of exons during RNA processing
