- Which of the following statements about conjugation is false?   After a F- cell has conjugated with an F+ cell, both cells would be F+.   Both Hfr and F+ bacteria have the ability to produce a sex pilus.   In F+ Ă F- conjugation, none of the bacterial chromosome is transferred; only the F factor is.   A Hfr strain usually transfers the entire bacterial chromosome to the recipient cell.   F' Ă F- conjugation can produce a partially diploid bacterial cell.arrow_forwardGenetic information can be transferred horizontally from one bacterial cell to another cell of the "same generation" (versus daughter cells), leading to genetic recombination, by all of the following EXCEPT:  A. Gene expression (transcription/translation/protein synthesis) B. Transformation C. Conjugation D. Transduction E.

It contains genes necessary for replication of the donor's F plasmid. can occur. It allows auxotrophic bacterial cells to survive on minimal medium so that conjugation It contains genes that force recombination between the donor and recipient chromosomes. It contains genes necessary for the formation of the pilus. O It degrades the chromosome of the recipient cell after conjugation.arrow_forward
- Assume that there are horizontal gene transfers between two completely different bacterial species. In one case it is a plasmid that is transmitted via conjugation, in the other case it is it is a part of the bacterial chromosome that is transferred via transformation. In which of the two cases is it likely that the transferred DNA will be present? left and can function in the recipient cells? Explain the biological background to your answerarrow_forwardDraw a diagram/figure to explain the conjugation process (e.g. use PowerPoint or draw one by hand and include a photo of it). You should include in the diagram the F- recipient, Hfr Donor and the transconjugant/recombinant recipient. Make sure to include the genes encoding for Leucine, Threonine, Thiamine and Streptomycin resistance in your diagram. How does an Hfr strain of coli transfers chromosomal DNA to an F- strain? What determines how much of the chromosomal DNA is transferred?arrow_forwardChoose the one answer that fits best. Which of the following statements regarding bacteria is NOT correct?  a. During conjugation, two bacteria exchange genetic information directly via pili  b. Bacterial populations have a higher mutation rate because their DNA Polymerases do not have proofreading capability  c. Bacterial growth by binary fission is exponential and each division usually takes only a couple of hour or less  d. Plasmids carry just a few genes and are replicated independently from the bacterial chromosome  e. Cocci that are arranged in clusters/bunches are called staphylococciarrow_forward
- If you wish to create an E. coli cell that is immune to phage lambda, which of the following genes should be incorporated into genomic DNA in the E. coli cell? Select one: a. N gene O b. Cro gene ĐŃ. Cl gene O d. SSB genearrow_forwardBacteria exposed to viruses incorporate sections of the virusâs DNA into the CRISPR array sequences in their genome. This mechanism allows bacteria to fight off the viruses, like an immune response: the information in CRISPR spacers served as âcoordinatesâ for recognizing and cutting up invading DNA sequences. Describe what might happen under the conditions described after a bacteriophage infects a bacterial cell and releases its DNA into the bacterial cell.  Explain why: 1. The invading phage DNA is recognized by the Cas proteins but not inserted into the CRISPR array region of the bacterial genome: The bacteria will be unable to elicit an immune response and will succumb to the phase infection 2. The cas genes on the bacterial genome contains a missense mutation that increases its cleavage/cut activityThe bacteria will elicit an immune response that will successfully fight the phage infectionarrow_forwardDuring the late stage T4 phage infection, the phage DNA is synthesized by Select one: Đ°. the DNA polymerase encoded by T4 genome. the ADP-ribosylated DNA polymerase encoded by E. coli genome.
