A cell contains fertility (F) plasmid that allows it to produce a structure for exchanging DNA with another cell. What structure is coded for by the genes of this plasmid?

Sex pilus or pilus

Explanation:

The donor bacterial cells during conjugation have a fertility plasmid. They are called F + cells. The F genes present on the F plasmid encode enzymes. Some of the genes of F plasmid also code for the formation of sex pilus which is the long and thread-like structures present on the bacterial cell surface. Sex pili are involved in the process of genetic recombination. During conjugation, the sex pilus serves to recognize the surface of F - cell and forms a cytoplasmic bridge between the F + and F - cells to facilitate DNA transfer.
