Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When bacteria move DNA from one cell to another through a hollow bridge this is called
A
binary fission
B
conjugation
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -In conjugation, DNA is transferred from one bacterium to another. After the donor cell pulls itself close to the recipient using a structure called a pilus, DNA is transferred between cells. In most cases, this DNA is in the form of a plasmid.

Detailed explanation-2: -Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells. This takes place through a pilus. It is a parasexual mode of reproduction in bacteria.

Detailed explanation-3: -Conjugation is the process by which one bacterium transfers genetic material to another through direct contact. During conjugation, one bacterium serves as the donor of the genetic material, and the other serves as the recipient. The donor bacterium carries a DNA sequence called the fertility factor, or F-factor.

Detailed explanation-4: -Conjugation is a gene transfer process in which a recipient bacterium receives DNA from a donor bacterium by cell-to-cell contact through conjugative pili. Conjugation is mediated by certain plasmids or transposons.
