3of 3 9. The figure below represents the primary transcript of a gene that contains four exons (A, B, C, D) and two introns. The dark block in exon B indicates the position of an additional stop codon; the normal start and stop codons for translation are present in exons A and D respectively.

Genes in eukaryotes are often organized into exons and intrans, which require splicing to produce an mRNA that can be translated. The gene organization is the order of the DNA segments that comprise the gene starting with the promoter, the first exon, the first intron, the second exon, and so on. The interspersed intrans can make gene identification difficult in eukaryotesparticularly in higher eukaryotes with many introns and alternative spliced mRNAs. Prediction of many genes and their organization has been...

OLU Ucues Assignment 4c. In eukaryotes, genes are composed of exons and introns, with only exons included in the mRNA. Each gene also has its own adjacent promoter, to which the transcribing enzyme RNA polymerase binds. Related genes may be clustered together on the same chromosome as a “gene family." Answer each of the following questions in the answer box of the assignment. You may also write the answers directly into the assignment document and then upload your answers. Number...

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...

12. Humerus bones from the same species of animals tend to have approximately the same length-to-width ratios. Forty-nine (49) fossils of humerus bones were unearthed at an 2/1 archeological site where species A is believed to have inhabited. The sample mean ratio is 9.254, and the sample standard deviation is 1.201. Suppose you want to find out whether the unearthed bones are from species A. It is known that the mean length-to-width ratio of species A is 9.0. The specific...

Consider an important protein like beta-galactosidase, which breaks down lactose. Many bacterial species have beta-galactosidase. But that doesn't mean that the amino acid sequence of beta- galactosidase in all those bacterial species is exactly the same. Far from it. As bacteria diversified into different species over evolutionary time, beta-galactosidase encoded in the genomes of the bacteria also diversified. However, we can assume that even though beta-galactosidase diversified, it was under pressure to maintain structure and function, because the reaction it...

Is what I have correct or wrong?
The diagrams below show very simplified species relationships for certain areas of African savanna. Recall what the direction of arrows means for each type of diagram. Then use these simplified diagrams to answer the next 3 questions. (Note: Real-world savannas support more species with more complex relationships.)

Among a total of 1000 college freshmen, a total of 450 have consumed energy drinks and 375 have used alcohol. Of those who . consumed energy drinks, 305 have used alcohol 1. Using energy drink consumption as the exposure and alcohol use as the "disease," create a contingency table with the data (1 points) 2. In order to determine internal validity of the study, what information (at least two things) would you want/need to know? Why is each important for...

1) You have two human liver cells (A and B) and you hypothesize that the insulin receptor gene in Cell A has a mutation in exon 1 and Cell B contains the wild type sequence. You extract genomic DNA from each of the cells. Of the following, what would be the most efficient (quick, precise and relatively cheap) way to test your hypothesis. a. Isolate protein from both cells, purify the insulin receptor, and determine the amino acid content. b. Sequence the...
