What must happen for transcription of the lac operon genes to take place?
Lac operon is a set of genes that regulates the digestion of lactose. In absence of lactose in the medium, the repressor protein binds to the operator that inhibit the transcription of structural genes such as beta galactosidase, lactose permease and transacetylase. This makes sure to avoid the enzyme synthesis when there is no need!Conversely, when the lactose present in the medium, an isomer of lactose called allolactose bind to the repressor protein, the conformational change in the repressor let it to detach from repressor hence the RNA polymerase can transcribe the structural gene. Although this may be enough for synthesis of structual gene the system is tightly regulated by a protein called CAP (catabolite activator protein) and glucose.Glucose is a preferred source of energy for cell when this desirable source is present, lactose need not be used as a energy resource. What happens is there will be low level of cAMP when there is high amount of glucose and this keeps CAP inactive.When there is low glucose levels, the cAMP would be higher, that binds to CAP to make it active, which in turn binds to the promoter that enhance the transcription of structural genes.Thus, for efficient transcription lac operon structural genes, lactose must be present where glucose must be absent.
What is the functional difference between enhancers and promoter proximal elements?
Enhancers are at considerable distances from the promoter and can be moved or inverted and still function. Promoter-proximal elements are close to the promoter and their position and orientation must be maintained.
Protein foods must be digested to what?
Amino Acids
In order to make a protein a cell must link together what?
In order to make a protein, a cell must link together amino acids by means of peptide bonds.
Why must protein-digesting enzymes be stored in the inactive form?
All the digestive enzymes are made of protein, yet some of them are protein-digesting enzymes. If they were all dumped into the same "pot" the protein digesting enzymes would quickly destroy the other enzymes, and the whole process would grind to a halt. The body must separate protein digestion from other processes.
What must occur for a message to be sent from the outside of the cell inside?
A signaling molecule must bind with a membrane protein.
What must occur for a message to be sent from the inside to the cell to the outside?
A signaling molecule must bind with a membrane protein.

In order for a protein to be an integral membrane protein it would have to be what?
the whole protein must be amphipathic but the surface itself must be hydrophobic.
Why you use skim milk to block the membrane in western blotting?
The membrane binds proteins unspecifically (it will bind any).Western blotting uses antibodies to probe the proteins bound to the membrane for the one you are testing for. The antibodies bind specifically to a particular protein that you have chosen and contain a label to allow identification of them on the membrane. In this way you can see whether or not the membrane, and therefore the tissue you are testing, contains a particular protein.Antibodies are proteins. This means the antibody would bind anywhere on the membrane, as well as on the protein you're looking for, rendering the results worthless (it will ALWAYS show positive). To stop the antibodies binding to the membrane, so that they only bind to the protein (if it exists) the membrane must be blocked (completely filled with protein) so that there is nowhere on the membrane for the antibody to bind.Since milk contains a generic mix of a relatively high concentration of known proteins, it is used to block the parts of the membrane that don't already have protein on so that the antibodies won't bind there. As it is very cheap and readily available, it is a good source of protein to use. It is unlikely that a Western blot would be needed for any protein that is contained in milk, but if that is the case an alternative mixture can be used.
In order for a lymphocyte to respond to an antigen the antigen must?
the antigen must bind to the receptor
How do you use jet pack on counter strike condition zero?
It is probably a mod. If it is superhero mod you must bind a key to +power# Otherwise u must bind something else.
