Final answer:
Conjugation experiments can map genes along the E. coli chromosome.
Step-by-step explanation:
Conjugation experiments can map genes along the E. coli chromosome. This statement is true. Conjugation is a process in which DNA is transferred directly from one prokaryote to another. In E. coli, the genes for conjugation are located on a plasmid called the F plasmid. During conjugation, the F plasmid can integrate into the bacterial chromosome, creating an Hfr cell. The transfer of genes from the Hfr cell to the recipient cell allows for mapping of the genes along the E. coli chromosome.
