Explain how the process of alternative splicing can result in the production of several different proteins from a single transcript from DNA.
Homework Answers
Alternative splicing is a method by which different proteins are produced from a single gene only. Most of the genomes of the eukaryotes consists of introns and exons. After the process of transcription, the introns are removed by spliceosomes and the remaining exons are ligated in different ways to produce different mRNAs . Different mRNAs lead to the formation of different proteins and this is how several different proteins are formed from a single transcript of DNA.

Alternative splicing is present in about 90% of human genes and can explain why our 20,325 genes can encode more than 1,000,000 proteins. Examine the image below of Gene X: Exon A Intron #1 Exon B Intron #2 Exon C 1. (2 pts) To create a transcript, which portions of this DNA sequence would be REMOVED during splicing? (Please be specific-ie. Exon A, Intron #2, etc.) 2. (3 pts) Gene X can encode 7 different proteins! Explain how this is...

Alternative RNA splicing is a method that apparently evolved for the production of many different polypeptides from the same pre-mRNA. Provide an example of alternative splicing. Make sure your answer is completely. Please can you type the answer. I don't understand the writing hand. Sometime. Thanks

Explain how a tissue-specific RNA-binding protein can lead to tissue-specific alternative splicing via splicing enhancers or splicing silencers. A.Trans-acting sequences that promote (splicing enhancers) or inhibit (splicing silencers) splicing are recognized by different classes of RNA-binding proteins (RBPs). B. Trans-acting sequences that promote (splicing silencers) or inhibit (splicing enhancers) splicing are recognized by the same class of RNA-binding proteins (RBPs) in different tissues. C. Cis-acting sequences that promote (splicing enhancers) or inhibit (splicing silencers) splicing are recognized by different classes...

Which statement about mRNA splicing is not accurate? Splicing is carried out by tRNA and associated proteins The C-terminal tail domain of RNA polymerade coordinates the processing (including splicing) of mRNA. The 2’ –OH in ribose is used during the splicing reaction. Alternative splicing can produce different proteins from the same genetic sequence in DNA Which describes the cellular role of chaperone proteins? Guide nascent proteins to their final destination in the cytoplasm Help nascent proteins fold into proper tertiary...

The human genome contains about 20,000 genes, but the human body can generate over 100,000 different proteins. How is it possible that humans have so few genes but can generate so many proteins? A. Humans likely have over 100,000 genes, but many have yet to be identified B. mRNAs of different genes can recombine to generate many different proteins C. the majority of proteins found within a cell are acquired from the environment D. mutations in DNA generate many versions...
Eukaryotic mRNAs can undergo alternative splicing.
Eukaryotic mRNAs can undergo alternative splicing. This is often used as a way to generate unique products in different cells of a multicellular organism. Let's assume that for a particular mRNA, exon 2 has normal 5' and 3' splice junctions, meaning that this exon will normally be recognized by the spliceosome for inclusion into the mature mRNA. Give me an explanation for how a different type of cell could block the inclusion of exon 2, so that it would not...
