Interactive question 19.3 Part 2
Are there cures for viral
plant diseases?
a. | As there are no cures for viral plant diseases, reducing the spread of infection and
breeding resistant varieties are the best approaches. | b. | There are cures for viral plant diseases. The
uptake of viricides through plant stoma by spraying or the uptake through root absorption effectively
administers treatment. |

answers to describing the steps
a. | bacterial chromosome | b. | prophage | c. | replicated bacterial
chromosome with prophage | d. | new phages | e. | phage
DNA | f. | Bacterium lyses, releasing phages. | g. | Occasionally, prophage exits bacterial

determine which cycle is entered. | i. | Bacterium reproduces, passing prophage to
daughter cells. | j. | New phage DNA and proteins are synthesized and self-assemble into
phages | k. | Large population of infected bacteria forms. | l. | Phage attaches to
host cell and injects DNA. | m. | Phage DNA integrates into bacterial
chromosome. |
