nucleic acid
tail section
What component of a virus is injected into the infected cell?

How does a lytic virus kill the cells that it infects?
It stops energy production by the cell's mitochondria.
It allows the cell's cytoplasm to enter the nucleus, which destroys the cell's DNA.
It causes the cell membrane to rupture.
It destroys chlorophyll molecules so that the cell cannot conduct photosynthesis.
Suppose that one virus infects one cell, and 300 minutes later 100 cells are dead (experienced lysis) due to viruses. Which of the following is most likely to describe when lysis occurred for those 100 cells?
Lysis occurred for zero cells in the first 150 minutes and for all 100 cells in the last 150 minutes.
Lysis occurred for 30 cells in the first 150 minutes and for 70 cells in the last 150 minutes.
Lysis occurred for 50 cells in the first 150 minutes and for 50 cells in the last 150 minutes.
Lysis occurred for 70 cells in the first 150 minutes and for 30 cells in the last 150 minutes.
