Homework Answers
C) Clots forming too easily.
Tissue plasminogen activator (tPA) is classified as a serine protease ( enzyme that cleave peptide bonds in proteins). It is thus one of the essential components of the dissolution of blood clots.Its primary function includes catalyzing the conversion of plasminogen to plasmin, the primary enzyme involved in dissolving blood clots.Recombinant biotechnology has allowed tPA to be manufactured in labs and these synthetic products are called recombinant tissue plasminogen activator.

expressed at high levels, comparable to its expression in the absence of trp 6. Based upon what you have learned about the E. coli trp operon, what could you say about expression of its structural genes in cells with large amounts of environmental trp, but expressing a mutant trp repressor that is unable to bind trp? A. The trp operon would be completely repressed due to the abundance of trp B. The trp operon would be transcribed much less than...

For Questions 4-18, consider the mutations described in the left-hand column below. Identify whether the Lac operon will be ON or OFF in each of the environments listed across the top. The expression of the normal (wild type) operon is given. Note that "ON" and "OFF" refer to whether the operon is expressed at high levels (ON) or basal//low/no levels (OFF). (Hint: mutations render the indicated site inactive while leaving the remaining part of the operon or protein functional.) Note...
