Bacterial with mutations in the lac operon have been created to study the functions of the different parts of the operon. In your analysis of one of the mutants, you noticed that the lac operon is transcribed, regardless of the presence of lactose, and the expression level increased in the absence of glucose. You theorize that the mutation is most likely to be in... the CAP site.

O lacl (repressor).
O laco (operator).
O All of these these mutations are possible.
Two of these mutations are possible.

not sure but try c two haploid cells

explanation:

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products

layer 3 is younger than layer 6.
