High frequency recombination cells arise when:
A)They have multiple F plasmids
B)A portion of the cell's F plasmid has been incorporated into the bacterial chromosome
C)Conjugation and transformation happen at the same time
D)Bacterial chromosomes do not break during conjugation

Question

Quizplus · Accepted Answer

High frequency recombination cells occur when a portion of the F plasmid (known as the Hfr region) is incorporated into the bacterial chromosome. This allows for the transfer of chromosomal genes from the donor cell to the recipient cell during conjugation at a high frequency, leading to recombination events. Multiple F plasmids (A) and simultaneous conjugation and transformation (C) do not necessarily lead to high frequency recombination. Bacterial chromosomes breaking during conjugation (D) would likely disrupt the transfer of genetic material and decrease the likelihood of recombination.
