Final answer:
SnRNPs are particles composed of RNA and proteins that play a crucial role in the splicing process. They bind to splice sites at each end of the intron and join together to form the spliceosome. option a,b,c are true.
Step-by-step explanation:
SnRNPs, or small nuclear ribonucleoproteins, are particles composed of RNA and proteins. They play a crucial role in the process of splicing, which involves removing introns from mRNA and connecting exons together to form a mature mRNA molecule.
Specifically, snRNPs bind to splice sites at each end of the intron, bringing the two sites together to form a large structure called the spliceosome. The spliceosome then carries out the necessary cuts and ligations to process the mRNA.
In summary, snRNPs are made up of both protein and RNA, they bind to splice sites at each end of the intron, and they join together to form the spliceosome.
