Textbook Question
Chapter 14, Problem 3P
Now that the sequence of the entire E. coli K12 strain genome (roughly 5 Mb) is known, you can determine exactly where a cloned fragment of DNA came from in the genome by sequencing a few bases and matching that data with genomic information.
| a. | About how many |
| b. | If you had purified a protein from E. coli cells, roughly how many amino acids of that protein would you need to know to establish which gene encoded the protein? |
| c. | You determine 100 nucleotides of sequence of genomic DNA from a different E. coli strain, but you cannot find a match in the E. coli K12 genome sequence. How is this possible? |

The Esp gene encodes a protein that alters the structure of the insulin receptor on osteoblasts and interferes with the binding of insulin to the receptor. A researcher created a group of osteoblasts with an Esp mutation that prevented the production of a functional Esp product (mutant). The researcher then exposed the mutant strain and a normal strain that expresses Esp to glucose and compared the levels of insulin in the blood near the osteoblasts (Figure 2).
Which of the following claims is most consistent with the data shown in Figure 2 ?
A Esp expression is necessary to prevent the overproduction of insulin.
B Esp protein does not regulate blood-s
