Question

Through David U-tube, Phages crossed the filter and ________ and ______ bacterial cells. Some of the phages occasionally package pieces of the chromosome from the infected bacteria and when spread gave other auxotrophic bacteria the genes needed to grow in minimal media.

Answer 1

Bacteriophages can transfer genetic material between bacteria through transduction, allowing recipient bacteria to acquire new genes.

Step-by-step explanation:

Bacteriophages are viruses that infect bacterial cells and can transfer genetic material between bacteria in a process known as transduction. In the specific case mentioned, the phages crossed the filter and infected bacterial cells. Some phages occasionally packaged pieces of the infected bacterial chromosome and transferred them to other bacteria, providing the recipient bacteria with the genes needed to grow in minimal media.
