how would alterning patterns of gene expression in prokaryotes would most likely serve an organism's survival? In a single point mutation, when the RNA and amino acid changes it is called ? what is the DNA sequence called?: 3”TTC ATT TAC TTT CGT TCA TAT TGT ACG ACT CGG TTA5”
In the experiment of Figure shown , a met− bio− thr+ leu+ thi+ cellcould become met+ bio+ thr+ leu+ thi+ by a (rare) double mutationthat converts the met− bio− genes into met+ bio+. Likewise, a met+bio+ thr− leu− thi− cell could become met+ bio+ thr+ leu+ thi+ bythree mutations that convert the thr− leu− thi− genes into thr+ leu+thi+. From the results of Figure shown, how do you know that the occurrenceof 10 met+ bio+ thr+ leu+ thi+ colonies is not due to thesetypes of rare double or triple mutations?
Which of the following prokaryotic cells would probably not be “competent” at transformation? an Escherichia coli cell blasted with a “gene-gun” carrying DNA on gold particles an Escherichia coli cell treated with dimethyl-sulfoxide (DMSO) a Streptococcus pneumoniae cell with no special treatments an Escherichia coli cell with no special treatments E. an Escherichia coli cell treated with calcium
Which of the following is NOT a method by which bacteria can be resistant to antibiotics? Select one: a. Utilise an alternate pathway of gene expression that is not targeted by the antibiotic. b. Alter the binding site of the antibiotic, to either prevent it binding, or remove it from the site. c. Production of enzymes that bind to and break down the specific antibiotic. d. Production of a cell membrane pump that translocates antibiotics outside the cell. A potential side effect of antibiotic use is a secondary bacterial or fungal infection, usually associated with regions like the skin, upper-respiratory tract or genitalia. What is the most likely reason for the formation of these secondary infections? Select one: a. Antibiotics do not work on viruses, so they are able to establish infections in these locations. b. Organisms that are antibiotic resistant are usually more virulent, meaning they can survive and cause infection. c. The antibiotic kills off normal flora, providing an…

Which of the following would best ensure that a kidney cell and a liver cell from the same person would express different genes? Group of answer choices differences in introns unique sets of transcription factors they only have specific genes unique sets of promoters 2. Refer to the metabolic pathway illustrated. If A, B, and C are all required for growth, a strain mutant for the gene encoding enzyme A would be able to grow on medium supplemented with which of the following nutrient(s)?
Bt eggplant is a genetically-modified eggplant developed by Filipino scientists. It was developed to become pest-resistance containing the gene of the bacterium Bacillus thuringiensis which contains toxins that are lethal to some insects including the pest bollworm. Currently, it is under controversy because of a legal battle between its supporters and those who are against it. Should the government ban the production, commercialization and consumption of the said Product?
In 2005, Frederick Blattner and his colleagues foundthat E. coli cells have a global transcriptional programthat helps them forage for better sources of carbon. Many genes, including genes needed for bacterial motility, are turned on in response to poorer carbonsources so that the bacteria can search for better nutrition. You now want to search for genes that regulatethis response. How could you use lacZ fusions to tryto identify such regulatory genes?
Each species of bacteria has its own distinctive cell surface. Thecharacteristics of the cell surface play an important role in processessuch as conjugation and transduction. For example, certainstrains of E. coli have pili on their cell surface. These pili enableE. coli to conjugate with other E. coli and also enable certain bacteriophages (such as M13) to bind to the surface of the E. coli andgain entry into the cytoplasm. With these ideas in mind, explainwhich forms of genetic transfer (i.e., conjugation, transduction,and transformation) are more likely to occur between different speciesof bacteria. Discuss some of the potential consequences ofinterspecies genetic transfer.
