Some examples of ribonucleoproteins include the signal recognition particle (SRP), telomerase, and small nucleolar ribonucleoproteins (snoRNPs). These complexes contain RNA molecules bound to proteins and play roles in various cellular processes such as protein synthesis, telomere maintenance, and ribosomal RNA processing.

What is a riboprotein?
riboNucleoproteins are protein+RNA. The Ribo means it is RNA and not DNA (deoxyribo) nucleotides. Nucleotides (RNA or DNA) can hold onto proteins and subsequently react with substrates or attach to other macromolecules such as proteins. Some proteins will not work without nucleotides attached. Ribosomal proteins, on the other hand, are proteins that work with ribosomes. There are about 79 proteins that interact with ribosomes.
What is the function of snRNA?
snRNA (small nuclear RNA) is involved in RNA splicing, a process in which introns are removed from pre-mRNA molecules, and exons are joined together to produce the final mRNA transcript. snRNAs combine with protein factors to form small nuclear ribonucleoproteins (snRNPs) that recognize specific sequences at the splice sites and facilitate the splicing process.
What is the function of snRNP?
The action of snRNPs is essential to the removal of introns from pre-mRNA, a critical aspect of post-transcriptional modification of RNA, occurring only in the nucleus of eukaryotic cells. Additionally, U7 snRNP is not involved in splicing at all, as U7 snRNP is responsible to process the 3′ stem-loop of histone pre-mRNA.
What is the difference between snRNA and snRNP, and how do they function in the process of RNA splicing?
snRNA stands for small nuclear RNA, which is a type of RNA molecule involved in RNA splicing. snRNAs are components of small nuclear ribonucleoproteins (snRNPs), which are complexes of snRNA and proteins. snRNPs function in the splicing of pre-mRNA by recognizing specific sequences at splice sites and catalyzing the removal of introns from the pre-mRNA molecule. In summary, snRNA is the RNA molecule, while snRNP is the complex of snRNA and proteins that function in RNA splicing.
What types of molecules catalyze RNA splicing?
Small nuclear ribonucleoproteins (snRNPs) are the main group of molecules that catalyze RNA splicing. These snRNPs consist of both RNA and protein components, and they play a crucial role in the spliceosome complex, which is responsible for catalyzing the removal of introns and joining of exons during pre-mRNA processing.
What does SNURPS stand for?
small nuclear ribonucleoproteins which "splice" introns
How are splice sites recognized?
Splice sites in mRNA are recognized by the spliceosome, a complex of proteins and small nuclear ribonucleoproteins (snRNPs). The spliceosome identifies the consensus sequences at the splice sites, including the 5' splice site, the branchpoint site, and the 3' splice site. The spliceosome machinery then removes introns and ligates together exons to produce the mature mRNA transcript.

What is the function of the spliceosome?
In eukaryotic organisms, genes consist of exons and introns. Exons are regions that are transcribed into mature messenger RNA, and eventually translated into protein. Interspersed within the exons are introns, regions of non-coding DNA. Introns must be removed from the initial transcript of mRNA before the final mature transcript is sent to the ribosome for translation into protein. This removal is done in a coimplex protein structure called the spliceosome. The spliceosome splices out the non-coding introns from the primary mRNA transcript, and stiches the exons back together into the mature mRNA transcript.
