You have recovered a strain of E. coli with a null mutation of the gene for catabolite activator protein (CAP). Which of the following do you expect to be true regarding the expression of a completely wild-type operon? Please note, more than one may be true.
A) Both beta-gal and permease will be made constitutively.
B) CAP protein will be bound irreversibly to the lac promoter.
C) Other operons coding for enzymes of degradative pathways for other sugars (e.g. maltose, arabinose, etc.) will be effectively non-inducible?
D) The lac repressor will be unable to bind to the operator when lactose is absent.
E) The lac repressor will be unable to bind to the operator when lactose is present.
F) cAMP alone will bind to the CAP binding site at the lac promoter.

A plasmid digest with BamHI produced 2 kb and 4 kb fragments. Digest of a plasmid with HindIII produced 6 kb fragment. Double digest with both enzymes produced 1 kb, 2 kb and 3 kb fragments. Sketch a plasmid map.
All through other periods of time, Tony seems very "down." throughout these times he does not take care of himself. He seems to want to sleep all the time, and he often makes thinly veiled references to wanting to commit suicide.
Thiol proteases are a widely distributed group of proteases with a mechanism somewhat similar to that of the serine proteases (the family of enzymes which includes chymotrypsin).
Discussing the significance of the neurotransmitters within the neurotransmission. Describing a relationship between the dietary fat intake and related health concerns.
Independent assortment during meiosis deals with Mendel's fourth postulate. It can provide genetic diversity among gametes in meiosis as well as crossing over.
