A reporter gene--that is, a
gene whose activity is relatively easy to detect--is commonly used
to study promoter activity under a variety of investigative
circumstances. Recombinant DNA technology is used to attach such a
reporter gene to the promoter of interest, after which the
recombinant molecule is inserted by transformation or transfection
into the cell or host organism of choice. Green fluorescent protein
(GFP) from the jellyfish Aequorea victoria fluoresces green when
exposed to blue light. Assume that you wished...

Which of the following is NOT true of the Rb protein? a. It inhibits gene expression by binding to a gene regulatory protein. b. In the absence of mitogen it promotes cell proliferation. c. Its activity is controlled by phosphorylation. d. It is a tumor suppressor protein. e. None of the above (= all of the above are true).

In the lac operon, 1 codes for the repressor protein, P is the promoter which is necessary for binding RNA polymerase, O is the operator, and Z codes for the B-galactosidase. Assuming (+) denotes the wild type for a particular locus, (-) denotes a lack of a particular gene product or function, O^c is a constitutive operator, and I^s is a super repressor. Use a "+++" sign to indicate that significant quantities of functional B-galactosidase are present, a '+' sign...

If a protein has 200 amino acids, and the gene that codes for it has 50 percent intron nucleotides, the number of nucleotides in the gene will be approximately: Select one: a. 200 b. 400 c. 600 d. 1200 e. 1000

In pea plants, there is a gene called the pod gene. This gene codes for a protein that limits the number of pea pods the plant can form. Farmers want to grow pea plants that produce more pods, so a scientist develops a chemical that binds to the pod protein and inactivates it. The scientist hypothesizes that exposing plants to the chemical will cause them to produce more pods. Describe a good experiment to test the scientist's hypothesis. Also describe...

1. Beadle and Tatum used which of the following organisms to support their one gene one enzyme concept a) E coli b) Drosophilia c) Neurospora d) Salmonella e) Homo sapien 2. Garrods concept regarding the relationship between the gene and metabolism can best be described as: a) one gene - one polypeptide b) one mutant gene - one metabolic block c) one gene - one metabolism d) one gene - one enzyme e) one gene- one transcript
