The genes for both the α- and βglobin chains of hemoglobin contain introns (i.e., they are split genes). How would this fact affect your plans if you wanted to introduce the gene for α-globin into a bacterial plasmid and have the bacteria produce α-globin?

- List three differences between a plasmid and a chromosomearrow_forwardList three important characteristics of plasmids and their functionarrow_forwardBacterial conjugation has medical consequences. For example, certain plasmids contain genes that code for toxins. The causative agent of a deadly form of food poisoning, E. coli 0157, synthesizes a toxin that causes massive bloody diarrhea and kidney failure. This toxin is now believed to have originated in Shigella, another bacterium that causes dysentery. Similarly, the growing problem of antibiotic resistance is partly attributable to the spread of antibioticresistant genes among bacterial populations. Antibiotic resistance develops because antibiotics are overused in medical practice and in livestock feeds. Suggest a mechanism by which this extensive use promotes antibiotic resistance.arrow_forward
- Explain the basis for the following statement: Transcription of two genes on a plasmid can occur without the concomitant action of a topoisomerase, but only if those two genes are oriented in opposite directions.arrow_forwardExplain, with the aid of a hand drawn diagram, the life cycle of bacteriophage T4.arrow_forwardoutline the sequence of events that comprise the mechanism used by a bacteriophage in order to infect a bacteria cell.arrow_forward
- Which of the following is NOT a mechanism by which plasmids inerease the possibility of being present in the new generation of cells? A) O They can be present at a high number so that some copies will end up in each new cell after cell division. B) O They encode traits such as antibiotic resistance that are required for growth in some environments. C) O They cause the cell to replicate much more rapidly than cells that do not have plasmids. D) O They may carry host survival genes and self-preservation genes.arrow_forwardOutline the sequence of events that compromise the mechanism used by a bacteriophage in order to infect a bacteria cell?arrow_forwardIf we were to examine a strain with the F plasmid inserted into the same site of the bacterial chromosome, but in the reverse orientation: a) What would the order of gene transfer be? Include all of the genetic markers including the amino acid and nucleic acid metabolism genes and streptomycin resistance. b) What cell types would be able to grow on the NA vs ECM media types? Be sure to include the genotypes of the cells that would grow. Remember that NA provides all nutrients the bacteria needs + no antibiotic and HCM = minimal medium + glucose + has streptomycin antibiotic c) Would we still be able to perform our mapping? Why or why not? (Hint: refer to part b above)arrow_forward
