Textbook Question
Chapter 10, Problem 15P
In Problem 14, cDNAs F and G could not be found in cDNA libraries (from any tissue) prepared using the method shown in Fig. 10.4. The reason is that the corresponding transcripts do not have poly-A tails.
a. | Why is the lack of poly-A tails not surprising in light of your answer to part (d) of Problem 14? |
b. | Why does the lack of poly-A tails present a difficulty for the method diagrammed in Fig. 10.4? |
c. | Outline how you might adjust the protocol in Fig. 10.4 so as to find the cDNAs F and G annotated in the Genome Browser |

A site-directed mutagenesis experiment was done on the catalytic triad of the serine protease subtilisin where all of the amino acids of the catalytic triad were mutated to alanine. The triple mutant enzyme was characterized kinetically and the mutant displayed a thousand-fold (103) rate enhancement over the uncatalyzed reaction. Explain the source of this rate enhancement. (The native wild-type subtilisin has a rate acceleration of 1010, when compared to the uncatalyzed reaction.)
After Drosophila DNA has been treated with a restriction enzyme, the fragments are inserted into plasmids and selected as clones in E. coli. With the use of this “shotgun” technique, every DNA sequence of Drosophila in a library can be recovered.a. How would you identify a clone that contains DNA encoding the protein actin, whose amino acid sequence is known?b. How would you identify a clone encoding a specific tRNA?
The IMD2 promoter contains three upstream transcription start sites (TSS) that are utilized under high GTP conditions and a single downstream TSS (-106) that is normally only utilized under low GTP conditions. In a wild type cell, expression of IMD2 mRNA only occurs if transcription initiates from the -106 TSS. In 300 words or less, describe: 1.) The normal function of Ssl2, and 2.) why a mutation in Ssl2, that increases its catalytic rate, would allow expression of the IMD2 ORF under high GTP conditions. (Conditions under which the IMD2 ORF is NOT expressed in the wild type.)
