What is the evidence of conjugation in bacteria?

Evidence of conjugation in bacteria includes several key observations. First, the physical formation of a sex pilus (a hair-like appendage) between donor and recipient cells is a hallmark of conjugation. Additionally, the transfer of genetic material from the donor to the recipient is another significant piece of evidence, which can be confirmed by molecular techniques such as plasmid analysis or genetic sequencing. The presence of new genetic traits in the recipient cell, such as antibiotic resistance, after conjugation further supports the occurrence of this process. The identification of specific genes, like the F-factor, in the donor cell is also crucial in confirming conjugation.
