Homework Answers
Answer - C) Hfr Cell
Explanation - Hfr Cell is known as High-Frequency Recombination cell which contains a conjugative plasmid integrated into its chromosomal DNA. The homologous recombination occurs for the transfer of chromosomal DNA into the plasmid. This makes the Hfr cells capable of transferring the most DNA.

Why do different conjugating strains show different gradients of transfer? Group of answer choices A. Hfr plasmids pick up different bacterial genes when they excise from the chromosome. B. There is variation in the rate that each F+ strain transfers DNA. C. The Hfr plasmid can integrate into different locations in the bacterial genome creating different F+ strains that initiate transfer at different locations. D. The F+ plasmid can integrate into different locations in the bacterial genome creating different Hfr...

What statement about conjugation is true? Group of answer choices A. Hfr strains are more useful for genetic mapping than F+ strains because Hfr strains can conjugate with any strain, while F+ strains can only conjugate with F- strains. B. Hfr strains are more useful for genetic mapping than F+ strains because they recombine transferred genetic material in the recipient cell at a higher rate. C. Hfr strains are more useful for genetic mapping than F+ strains because Hfr strains...
