7. The following diagram shows a protein-coding gene and specifies the positions of its translational start and stop signals: Which of the following is correct? A) Upper is template strand, carboxy terminus of protein to right B) Upper is template strand, carboxy terminus of protein to left C) Lower is template strand, carboxy terminus of protein to right D) Lower is template strand, carboxy terminus of protein to left E) Either strand could be template on the basis of this information 8. A protein fragment has the following sequence: NH 2 -His-Met-Leu-Ile-Lys-COOH . The DNA template strand sequence (3´ 5´) would be 11. In a wild-type strain of Drosophila the size of a gene from the start to stop codon is calculated to be 2000 nucleotide pairs. However, the size of the mRNA molecule transcribed from this gene is estimated at 1200 nucleotides. The most likely explanation for this discrepancy in size would invoke the existence of 15. An individual that is heterozygous has Huntington's disease. The type of mutation this person has is called

Evolutionary Genetics Open-Ended Questions 1. In the chart below indicate by a “+” if the characterisic is present in at least some members of the group (bacteria, bacteriophages, eukaryotes). Use a “0” if the characteristic is absent in all members of the group. Bacteria Bacteriophages Eukaryotes (a) A large number (more than 1,000) of highly repeated sequences of DNA ___ ___ ___ (b) A membrane-bound nucleus ___ ___ ___ (c) DNA as its genetic material ___ ___ ___ (d) RNA as its genetic material ___ ___ ___ (e) Shine-Dalgarno sequences ___ ___ ___ (f) 5´ cap ___ ___ ___ (g) Open reading frames ___ ___ ___ (h) Introns ___ ___ ___ (i) Aminoacyl-tRNA synthetases ___ ___ ___ (j) Ribozyme ___ ___ ___ (k) Spliceosomes ___ ___ ___ (l) mRNAs with poly(A) tails ___ ___ ___ at their 3´ ends 2. Shown below is the structure of a Drosophila gene, divided into 10 segments, designated A– J. The gene contains three exons, two introns, a promoter, and a site in I for poly(A) addition.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
