Question
Chapter 17.3, Problem 1TYK
Summary Introduction
Introduction:
The exchange of genetic material between bacteria takes place by three methods- conjugation, transformation, and transduction. The temporary union for the transfer of genetic material between two bacteria or unicellular species is called conjugation. Bacteria come closer and transfer the material and get separated.

- In conjugation, when a bacterial F factor is transferred: the donor cell turns into a recipient cell the donor cell becomes F- chromosomal DNA is transferred in the mating the recipient cell becomes F- the recipient cell becomes F+arrow_forwardIn conjugation, how are donor and recipient cells brought intocontact with each other?arrow_forwardWhich 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+ × 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' × F- conjugation can produce a partially diploid bacterial cell.arrow_forward
- In gene mapping using generalized transduction, bacterial genes that are cotransduced are a. far apart on the bacterial chromosome. b. on different bacterial chromosomes. c. close together on the bacterial chromosome. d. on a plasmid.arrow_forwardWhich of the following statement about conjugation is TRUE: During F+ to F- mating, the donor becomes F-. During the Hfr to F- transfer, the recipient becomes F+. The whole bacteria genome may get transferred during Hfr mating. During the Hfr to F- transfer, some recipients become recombinants in which transferred fragment recombines with homologous region in the genome.arrow_forwardIf you are using a restriction enzyme that make 8 cuts in the Lambda phage DNA, how many bands (pieces) do you expect to be generated assuming each band is a unique size?arrow_forward
- Consider the following types of cells: F+, F-, Hfr, and F’ cells. Which of these four types of cells are capable of acting as a donor during conjugation? What genes does each cell that is capable of acting as a donor donate to the recipient cell?arrow_forwardA group of genetics students mix two auxotrophic strains of bacteria: one is leu+ trp+ his− met− and the other is leu− trp− his+ met+. After mixing the two strains, they plate the bacteria on minimal medium and observe a few prototrophic colonies (leu+ trp+ his+ met+). They assume that some gene transfer has taken place between the two strains. How can they determine whether the transfer of genes is due to conjugation, transduction, or transformation?arrow_forwardIn conjugation of a Hfr cell with an F- cell: a) the container cell becomes F + b) The container cell remains F- c) The donor cell becomes F- d) The recipient cell becomes Hfrarrow_forward
