Please classify each statement as describing transformation, conjugation, or transduction in bacteria. Bacteria can acquire plasmids from outside the cell. A bacterium that contains an F plasmid connects to a recipient bacterium that lacks an F plasmid with an appendage called a pilus, through which the plasmid is transferred. Some bacterial DNA fragments may be included when new phage particles are assembled. A cell can be treated to make it competent to take up DNA from its environment. When a...

Create a labeled diagram and describe the gene transfer process by which the Shiga toxin gene was picked up fromShigella dysenteriae and transferred to Escherichia coli. Be as specific as possible in your description of this process. Meaning be sure to label your donor and recipient cells as the bacterial species given depending on how the genes are being transferred.

You have created a mutant that is streptomycin resistant (s+),
has the ability to photosynthesize (p+), and is resistant to a
particular phage, P5 (r+). Your PI would like you to try and move
these traits into E. coli by means of generalized transduction.The
donor phage has the genotype s+ p+ r+, while the recipient
bacterium has the genotype s- p- r-. You carry out selection for
the phage resistance trait and then screen all of the r+
transductants for...

1. The type of genetic exchange between bacterial cells that can happen between isolated DNA and a live bacterial cell is: a. conjugation b. transduction c. transversion d. transformation 2. An Hfr strain of E. coli with genotype a+b+c+d+e+f+ is mated with an F¯ auxotrophic strain with the genotype a¯b¯c¯d¯e¯f¯. Conjugation is stopped at 10 minute intervals and the genotypes of the resulting conjugants are determined. The following results are obtained: after 10 minutes e+ after 20 minutes a+ e+...
