SB5f: Virus Life Cycles Keywords

Question 1

Bacterial lawn plate

Answer 1

A nutrient agar plate covered in a thin film of bacteria.

Question 2

Capsid

Answer 2

The protein coat of a virus.

Question 3

Cross-sectional area (of a cylinder)

Answer 3

Question 4

Lysis

Answer 4

When the cell membrane of a cell breaks open, releasing everything inside the cell.

Question 5

Lysogenic pathway

Answer 5

The pathway in a virus life cycle where the virus genetic material inserts into the cell’s genetic material and is replicated each time the cell divides.

Question 6

Lytic Pathways

Answer 6

The pathway where a virus enters a cell, takes over the cell’s replication process to produce more viruses, and causes lysis of the cell as the new viruses are released.

Question 7
