JordanA pilus is a protein appendage found on the surface of bacteria that helps in attachment to surfaces or other cells. Conjugation is a method of genetic transfer in bacteria where a plasmid is transferred from one bacterium to another through direct physical contact facilitated by a pilus. In essence, pilus is a structure, while conjugation is a process of genetic exchange.

What is the structure that allows conjugation to occur?
Conjugation in bacteria occurs through a structure known as a pilus, which is a filamentous appendage on the cell surface. The pilus facilitates the transfer of genetic material, such as plasmids, between bacterial cells during conjugation.
In bacteria genes may be transferred through a pilus which acts like a bridge in a process called?
In bacteria, genes may be transferred through a pilus in a process called conjugation. Conjugation allows for the transfer of genetic material, such as plasmids, between bacterial cells. This transfer of genes can contribute to genetic diversity and the acquisition of new traits in bacterial populations.
Does bacterial conjugation use cellular energy?
Yes, bacterial conjugation does require cellular energy in the form of ATP. This energy is needed for various processes during conjugation, such as DNA replication, movement of the conjugative plasmid between cells, and synthesis of conjugation pilus for cell-to-cell contact.
Is genetic material is transferred through a pilus in binary fission?
No, genetic material is not transferred through a pilus in binary fission. In binary fission, a parent cell divides into two identical daughter cells, and genetic material is replicated and distributed equally to each daughter cell during this process. Pilus is involved in bacterial conjugation, where genetic material is transferred from one bacterium to another.
What does bacteria do in the process of conjugation?
In conjugation, bacteria exchange genetic material through a tube-like structure called a pilus. This allows them to transfer DNA, such as plasmids, between cells. Conjugation enables bacteria to acquire new traits, such as antibiotic resistance, and increase genetic diversity.
