- A hypothetical gene for cephalosporin resistance is found to be carried by a transposon. Explain what a transposon is. Then explain how the cephalosporin resistance could be horizontally transferred between organisms by transformation, conjugation, and transduction. What steps/events would have to occur to allow the transposon to be transferred by each method. Also, explain how it could be transferred vertically between organisms.arrow_forwardA scientist uses transduction to map genes in a strain of E. coli. For this experiment, the donor strain is leu+ phe+lys-+arg+. The recipient is leu-phe-lys-arg- Co-transduction rates were • leut and phe+ = 29% • leu+ and arg+ = 46% • leu+ and lys+ = 6% Which gene is furthest from leu? lys phe arg leu Is the percentage is the chance of being co-transductionarrow_forwardDescribe two methods for transforming a vector into bacteria.arrow_forward
- Contrast Generalized and Specialized Transduction. Include at least 4 major points of contrast.arrow_forwardWhat must a vector contain?arrow_forwardWe have two specific strains of E. coli that have shown horizontal gene transfer (HGT) when mixed. To experimentally determine the method of HGT that is happening, the following conditions are set up in different tubes of culture media: A) Donor and recipient strain mixed together (control - no treatment). B) Donor and recipient strains mixed together, DNase added (can digest DNA in solution, not within cells).C) Special tube containing a membrane filter (with pores that allow DNA and viruses to pass through, but not bacterial cells) that separates two compartments. Donor strain is added on one side, the recipient strain on the other (they are separated by the filter).D) Donor and recipient strains mixed together, with chemical that inactivates viruses (chemical affects bacteriophages in solution so they are unable to attach to cells). The results: Tubes A, B, and D: HGT was observed. Tube C: HGT was NOT observed. Based on this, which type of HGT was occurring? Conjugation,…arrow_forward
