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.
What else can I help you with?
In a eukaryote what is a segment of a gene that codes for a protein?
A segment of a gene that codes for a protein is called an exon. Exons are the parts of a gene that are ultimately expressed as proteins after being transcribed and translated. They are interspersed with non-coding regions called introns.
The coding regions of a gene the portions that are expressed as polypeptide sequences are called?
exon
Are both intron and exon regions are transcribed into the primary transcript?
Yes, both intron and exon regions are transcribed into the primary transcript during transcription. However, only the exons are retained in the processed mRNA after introns are removed through the process of splicing.
What is an exon?
When a gene is transcribed to for an mRNA molecule, introns are removed and exons stay to be reattached to from one linear mRNA molecule again. This final RNA sequence then gets used by a Ribosome to form a protein
What are the differences between exon shuffling and alternative splicing in terms of their mechanisms and impact on gene expression?
Exon shuffling involves the rearrangement of exons between different genes, leading to the creation of new gene structures. This can result in the formation of novel proteins with new functions. On the other hand, alternative splicing involves the selection of different combinations of exons within a single gene, resulting in multiple mRNA transcripts and protein isoforms from a single gene. This increases the diversity of proteins that can be produced from a single gene, allowing for more complex regulation of gene expression.

Which oil spill was the worst?

What is an exon's role in DNA?
The exon codes for the opening sequence of DNA for protein synthesis. It is a sequence of nucleotides that code for the RNA to begin transcription of the DNA to RNA protein.
