Bacterial Recombination · Zoology

An Hfr strain of bacteria is characterized by:

  1. A free F plasmid floating within the cytoplasm
  2. Complete absence of any plasmids in the whole cell
  3. Integration of F plasmid into the chromosome
  4. Complete inability to carry out any conjugation
Show answer and explanation

Correct answer: Integration of F plasmid into the chromosome

In Hfr strains, the F plasmid is integrated into the bacterial chromosome. This allows chromosomal genes to be transferred during conjugation.
