Where do gene mutations occur?
on a gene it can occur on the promoter, intron-exon borders, poly-A-tail cleavage sites and on the exon
When does exon shuffling occur?
post transcription
When does splicing occur?
nucleus
What is exon skipping?
Exon skipping, also known as alternative splicing is a process whereby the exons are cut from a genetic sequence (pre-mRNA or hnRNA) and rearranged multiple ways into different mRNA molecules. This allows for a single gene to code for several proteins and isoproteins. Seen in Eukaryotes only.
Are Exons Cut After Transcription In Eukaryotes?
No. The Ex in Exon refers to Expression.Introns are nucleotide sequences within genes that are removed by RNA splicing to generate the final mature RNA product of a gene.
What would happen if RNA splicing didnt occur?
it will result into a non functional protien
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 is the birth name of Jim Exon?
Jim Exon's birth name is John James Exon.
Does splicing occur in prokaryotes?
in prokaryotes only self spilicing and tRNA splicing are present there is no splicosomes are present.
Does splicing occur naturally?
Yes, it only occurs in eukartoyic mRNA as they only have the non coding region (introns)
What is J. James Exon's birthday?
J. James Exon was born on August 9, 1921.
When was J. James Exon born?
J. James Exon was born on August 9, 1921.
