Protein splicing involves the excision of intervening peptide sequences called inteins from a precursor protein to produce the final functional protein, while RNA splicing involves removing introns and joining exons in pre-mRNA to form mature mRNA. Protein splicing occurs post-translationally in the protein after translation, while RNA splicing occurs co-transcriptionally during mRNA processing.

What are the kinds and functions of RNA molecule?
its function is to link amino acids during protein synthesis, and in a variety of RNA processing reactions, including RNA splicing, viral replication, and transfer RNA biosynthesis.
Can a single protein have multiple genes?
No, a single protein is typically encoded by a single gene. Genes contain the instructions for making proteins, and each gene is responsible for coding a specific protein. However, alternative splicing can allow a single gene to produce multiple protein isoforms with different functions.
What the difference between rna and dna in number of strands?
RNA is typically single-stranded, while DNA is double-stranded. RNA carries genetic information in some viruses and acts as a messenger between DNA and ribosomes during protein synthesis. DNA stores genetic information in most organisms and is the blueprint for the development, growth, and functioning of living organisms.
What happens before a RNA messenger is mature?
Before a messenger RNA is mature, it undergoes several processing steps in the cell nucleus. These steps include capping at the 5' end, splicing to remove introns, and adding a poly-A tail at the 3' end. This processing is essential for the proper functioning and stability of the mRNA molecule.
What is the difference between rna and dna in bacteria?
RNA is typically single-stranded, whereas DNA is double-stranded in bacteria. RNA is involved in protein synthesis and gene regulation, while DNA stores genetic information. RNA is more susceptible to degradation than DNA in bacteria.
What is the process called which removes introns from RNA?
RNA splicing
Alternating RNA splicing?
Alternating RNA splicing refers to a process in which different exons are included or excluded in the final mRNA transcript, leading to the production of multiple protein isoforms from a single gene. This process enables cells to generate diverse protein products from a limited number of genes, contributing to cellular complexity and functional diversity. Dysregulation of alternative splicing has been associated with various diseases, including cancer.

How do introns and exons relate to RNA splicing?
Introns are non-coding sequences in DNA that are removed during RNA splicing, while exons are the coding sequences that are joined together to form the final mRNA transcript. RNA splicing is the process by which introns are removed and exons are joined together to produce a mature mRNA that can be translated into a protein.
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.
Can a single protein have multiple genes?
No, a single protein is typically encoded by a single gene. Genes contain the instructions for making proteins, and each gene is responsible for coding a specific protein. However, alternative splicing can allow a single gene to produce multiple protein isoforms with different functions.
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 would happen if RNA splicing didnt occur?
If RNA splicing didn't occur, the pre-mRNA would not be processed properly to remove introns, resulting in an mRNA that contains irrelevant genetic information. This would prevent the proper translation of the mRNA into protein, likely leading to errors in protein structure and potentially disrupting cellular function.
RNA splicing involves the?
removal of introns and joining of exons in pre-mRNA to produce mature mRNA that can be translated into a protein. This process is carried out by a complex called the spliceosome, which recognizes specific sequences at the ends of introns to facilitate their removal and joining of exons. RNA splicing plays a crucial role in generating protein diversity and regulating gene expression.
What is the difference between the nucleus and the nucleus?
The nucleolus is a concentrated area of chromatin, RNA and protein that produces ribsomal RNA. The Nucleus simply stores the genetic information and synthesises DNA and rna. hope this helped/
What is the difference between transfer RNA messenger RNA?
messenger RNA is something that copies the coded message from DNA in the nucleus and carries the message into the cytoplasm.But transfer RNA is something that the cytoplasm carries an amino acid to the ribosome and adds it to the growing protein chain.
Difference between the DNA and RNA?
the difference is that DNA is a double helix and RNA is a single chain
