Which cell can transfer the most DNA? A)F⁺ cell B)F^-cell C)Hfr cell D)R cell E)B cell

Question

Quizplus · Accepted Answer

Hfr (high frequency of recombination) cells have a higher frequency of transferring chromosomal DNA during bacterial conjugation compared to other types of cells. This is because the F (fertility) plasmid, which contains the genes for conjugation, has integrated into the bacterial chromosome in the Hfr cell. This means that during conjugation, the entire bacterial chromosome can be transferred to the recipient cell, allowing for the transfer of the most DNA. The other options, such as B and E cells, do not refer to any specific type of bacterial cell and therefore cannot be chosen as the best option.
