Homework Answers
C) you analyze whether there has been alternative splicing by examining amino acids of very similar receptor gene.
Even after a gene has been transcribed, gene expression can still be regulated at various stages. Some transcripts can undergo alternative splicing, making different mRNAs and proteins from the same RNA transcript.

QUESTION 6 Assume you are studying a protein-coding gene, ACEX, which includes 4 exons as illustrated in the gene map below. The 5' UTR and 3' UTR segments are each 25 bp long. Exons 1 thru 4 are 100, 200, 300, 400 bp long, respectively. Each intron is 200 bp each. The locations of the relevant EcoRI sites within the ACEX locus are indicated, but the location of other restriction enzyme sites (like BamHI) are not shown." EcoRI probe EcoRI...

Name 2ors L! You are inte finding protein are interested in understanding how Top5 expression is regulated. Top5 is a microtubule protein. You study a cell line where Top5 expression is controlled by a signal, Ligl. When hinds to and activates the membrane bound recentor it activates the Ras protein, which activates atein kinase called PKF, which then phosphorylates Grp4 on T224. Grp4 is a gene regulatory Wotein that can only enter the nucleus when phosphorylated: Thos is not expressed...

Yet, all the cells in your body contain the same
genes (and same alleles). The difference across cell types
is that genes get selectively expressed (turned on or off)
based on the proteins needed for cellular function given their
environment.

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...
