Question
The F-factor is a group of genes that encode all the proteins necessary for a bacterial cell to make a sex pilus. The F-factor can either be in the genome (within the chromosome) of cell, or residing on extrachromosomal DNA (plasmid). Cells without the F factor are given the label "F-". The genetic material transferred from donor cells with the F factor is different depending on where the donor cell has the F factor encoded. Complete the table below, providing the names given to cells with the F factor, and the type of genetic material usually transferred by that donor (other than small plasmids that can always be exchanged by chance).Explanation / Answer
The F factor or the fertility factor is all that a cell of a bacteroum need for their sexual mode of reproduction. This factor is commonly asscoaited in a plasmid and gets transferred through the process of conjugation maong the bacterial cells through pili.
The second option if the "F factor on plasmid", this presence truly influences the mechanism to takes place and in the next column we can write a lebel of F+. This suggests that the cell is containing the F factor, after the transfter of its copy from one bacterium to another the recipients cell will be called F+ cells. The genetic material is transferred and there is a donor cell and another one is the recipient cell.
The third option is "F factor in chromosome", which is often known as the episome or the integrated plasmid with the chromosome. When thi episome needs it F+ factor to comes out and follow the same conjugation menthod it cures out of the chromosome. But soometime this cut out process takes some portion of the chromosome of even to lose some portion of the plasmid, and in this situation the transferred genetic material is called as F' (F prime). This is here too will have a donor and a recipient, this occurs over the transfter process through pili, when one cell could not transfter the whole thing the the situation gets inturrupted.
