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 carrying the fertility genes is integrated into the bacterial chromosome, creating an Hfr cell. During conjugation, the Hfr cell can transfer large portions of its chromosomal DNA to the recipient cell, leading to a high frequency of recombination. Multiple F plasmids (A) or simultaneous conjugation and transformation (C) do not necessarily result in high frequency recombination. The presence or absence of chromosome breaks (D) is not directly linked to the formation of Hfr cells.
