Question 8: In another protein-coding gene, you observe 20 fixed nonsynonymous substitutions and 10 fixed synonymous substitutions between humans and mice. Also, you observe 8 nonsynonymous variants and 5 synonymous variants in this gene within human populations. Is this gene under positive selection? Why? (2 points)

QUESTION 7 Consider the hypothetical gene show here. The gene coding sequence consists of 4 exons (shown in solid colors). The 5' UTR and 3' UTR are shown as striped boxes. 25 150 200 300 400 25 Based on the lengths of the exons, you should be able to calculate a rough estimate of the protein encoded by this gene, assuming that all 4 exons are translated and the protein does not undergo any significant processing (cleavage or chemical modifications)....

7. Open reading frames A protein coding gene includes the following sequence on one of its two DNA strands. Note that this segment (within an exon) does NOT include either the start codon or the stop codon for this gene. However, because five of the six potential reading frames (3 on each DNA strand) in this region include stops, only the true reading frame remains "open" through this segment. Therefore, it is possible to unambiguously decode (translate) this segment of...

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...

Question 2: Transcription, RNA Processing and Translation A particular gene codes for a mature mRNA transcript containing 1200 bases, which is translated into a protein containing 300 amino acids. A. How long is the coding sequence in this mRNA and how many nucleotides are in the UTRs? For the purposes of this question we are ignoring the G’ cap and the polyA tail. B. A mutant form of the gene created by one nucleotide being changed to another nucleotide also...

QUESTION 7 If the MC1R protein is 317 amino acids long why are there 954 base pairs in the coding region of the gene? Each amino acid has a mRNA codon and DNA triplet consisting of a three-base sequence. (317 x 3951 plus a stop codon (951-3-954) to signal the end of translation) Because there are 317 proteins in the MC1R code. mutant proteins always have 954 base pairs. Each amino acid has a mRNA codon and DNA triplet consisting...

QUESTION 1: You are inserting a gene into an MCS found within the LacZ gene. Using blue/white colony selection, why could you assume that white colonies have modified plasmids? a. A blue colony means the LacZ reading-frame was disrupted b. A blue colony means your gene has mutations c. A white colony means the LacZ reading-frame is intact d. A white colony means the LacZ reading-frame was disrupted QUESTION 2: You are performing a PCR using primers with a sequence perfectly...

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...
