ANSWER:
Project: You want to make a cat that glows in the dark (its nose, ears, and tail should glow). Choose the best answer.
9) To get started on this project, you isolate and cut out the gene in a jellyfish that codes for the green fluorescent protein (GFP). The next thing you need to do is attach this gene to the correct promoter so that you can be sure it is expressed appropriately in the cat. Which of the following promoters should you use?
a) any promoter is fine
b) the original promoter found in the jellyfish
c) a promoter from a gene that is expressed in cells of the cat's nose, ears, and tail
10) You are now ready to transfer the piece of recombinant DNA you have prepared to the cat. You want to be sure that the transgenic cat you create will be able to pass the fluorescence on to its offspring. What is the best type of cell to transfer the recombinant DNA to?
a) an unfertilized egg
b) a fertilized egg
c) somatic cells of an adult cat

- Objective: Get a sense of how genomics, the study of the genome in its entirety,needs to think about how to go about its research. Geonomic DNA is broken up into fragments. The 5’ and 3’ ends of each fragment(a “read”) are sequenced. The sequenced reads are assembled together intocontiguous sequences (“contigs”) based on sequence similarity. The idea is to sequence enough random fragments so that every nucleotide in thegenome is represented on some read. The number of such fragments needed iscalled the coverage, c. The coverage c can be calculated by the formula RL/G, where R is the number ofreads sequenced, L is the average length of a read and G is the total length of thegenome. The units of length are bases (b) or base pairs (bp). Consider a genome whose length is 1000 bp. “Shotgun” sequencing techniquesare applied to the genome, resulting in 20 reads, with an average length of 50 bp.A very important point is that, even though 20 x 50 = 1000, there is no guaranteethat ALL…arrow_forwardObjective: Get a sense of how genomics, the study of the genome in its entirety,needs to think about how to go about its research.
