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 of RNA-binding proteins (RBPs). |
| D. Cis-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. |
Homework Answers
The answer is A.Trans-acting sequences that promote (splicing enhancers) or inhibit (splicing silencers) splicing are recognized by different classes of RNA-binding proteins (RBPs).
Since trans-acting sequences are those which are synthesized at a location other than the gene they're going to act on, they are recognized by different classes of RBPs.
Also, the sequences that promote splicing are enhancer and those which inhibit splicing are splicing silencers.

1. trans-acting factors are able to regulate target genes from any chromosome, whereas cis-acting elements can only regulate genes located in the same chromosome. a. True only in operons. In Eukaryotic systems, trans-acting factors only regulate genes in the same chromosome. b. True only in Eukaryotes. Prokaryotes don’t have cis-acting elements. c. True for any organism. d. False. The statement is erroneous 2. Unlike activators, repressors never affect chromatin structure. Repressors inhibit transcription only by binding to the binding sites...

three part question!!!!
Lab Activity for RNA Processing: p53 Isoforms Isoforms, simply defined, are different proteins created from the same genomic sequence. These differences can be created by a variety of mechanisms, including alternative splicing, the usage of different promoters, and the usage of different start codons. The p53 gene (usually called Tp53) is located on the short arm of chromosome 17 in the human genome. It has some unique gene topography, including one non-coding exon and very long intron...

Genetics Worksheet Week 3: Gene Regulation and Epigenetics 1. Duchenne muscular dystrophy is caused by a mutation in a gene that is 2.5 million nucleotides in length and encodes a protein called dystrophin. The dystrophin protein itself is 3684 amino acids in length. Calculate below the approximate size of the mRNA that encodes dystrophin. Approximately what percentage of the gene that encodes dystrophin is intron sequence? The human genome encodes a much greater variety and number of proteins than the...

please answer all that you can 1. You have genetically engineered green fluorescent protein (GFP) containing a KDEL sequence (GFP-KDEL). When GFP-KDEL is expressed in normal human fibroblasts and examined using fluorescence microscopy, the fluorescence appears diffuse across the cytoplasm. How would you explain this observations given that KDEL is supposed to be an ER-specific sorting sequence? A. This engineered GFP would not have a hydrophobic signal sequence to get it into the RER in the first place. B. The...

2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
