How Does a Phage Transfer DNA from One Bacterium to Another

question 45

Multiple Choice

How does a phage transfer DNA from one bacterium to another?

• A) Phages form a bridge between bacterial cells that allows DNA to pass from the host cell to the recipient cell.
• B) Phages form a bridge between bacterial cells that allows DNA to pass in both directions between the two cells.
• C) Phages lyse bacterial cells, releasing bacterial DNA into the environment, which is taken up by other phages for transfer to new cells.
• D) When phages assemble in an infected bacterial cell, they may incorporate host DNA; released phages may attach to other cells and inject the bacterial DNA into those cells.
• E) Phages attach to receptors on bacterial cells and receive some of the target cells' DNA; the phages release this DNA into the environment to be taken up by other bacterial cells.
