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?
Yes. A protein produced by multiple genes are cased by fusion genes. Usually a protein is translated from a mRNA which is transcribed from a DNA. After transcription, RNA is rearranged by so-called RNA splicing in which some of short sequences are selected(Exon) or deleted(Intron). During the splicing two different genes can join together and it is called trans-splicing. After trans-splicing, mRNA is translated into a protein, so the protein has two genes. Most cases these fusion genes are oncogenes which cause Cancerous diseases.
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?
RNA is spliced (cut) in order to make it mature. This involves splicing out the introns and leaving the exons - these are the segments that code for a protein. This means that when mRNA leaves the nucleus, it only contains the segments that directly code for a protein.
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?
An alternative RNA splicing is a process by which the exons of the RNA produced by the transcription of a gene are reconnected in multiple ways during RNA splicing, so as to allow production of multiple forms of protein from one gene.
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.

How do introns and exons relate to RNA splicing?
Before the RNA leaves the nucleus, the introns are removed and the exons are joined together, producing an mRNA molecule with a continuous coding sequence. This process is called 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.
Can a single protein have multiple genes?
Yes. A protein produced by multiple genes are cased by fusion genes. Usually a protein is translated from a mRNA which is transcribed from a DNA. After transcription, RNA is rearranged by so-called RNA splicing in which some of short sequences are selected(Exon) or deleted(Intron).

Most cases these fusion genes are oncogenes which cause Cancerous diseases.
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 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/
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 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.
Are exons or introns spliced out during the process of RNA splicing?
During the process of RNA splicing, introns are spliced out, while exons are joined together to form the mature mRNA molecule.
