|
|
Term
| What is Methanogens like? |
|
Definition

|
|
Term
| What are Thermoacidophiles like? |
|
Definition
| they can live in water that is extremely hot and acidic, near volcanic islands |
|
|
Term
| What are extreme halophiles like? |
|
Definition
| live in extremely salty conditions, salt is beneficial to their growth because they use salt to generate ATP |
|
|
Term

| What are the steps in the lytic cycle? |
|
Definition
| 1 Attatchment and absorption, injection and penetration, viral replication and assembly, release. |
|
|
Term
| describe the attatchment and absorption step of the lytic cyle? |
|
Definition
| The bacteriophage absorbs to the cell wall of the bacterium. The attatchment sites on the virus bind to the corresponding receptors on the host cell wall. |
|
|
Term
| Describe the injection step of the lytic cycle. |
|
Definition
| The bacterophage injects its genome into the bacterias cytoplasm. |
|
|
Term
| Describe the viral replication and assembly step of the lytic cycle |
|
Definition
| The viral genome directs its host cells metabolic machinery to make viral enzymes and parts. The capsids assemble around the viral genomes as the viral tails assemble and replicate |
|
|
Term
| Describe the release step of the lytic cycle |
|
Definition
| the bacteriphage is released by lysis of the bacterium. A bacteriphage coded enzyme breaks down the peptidoglycan in the bacetrial cell wall casusing osmotic lysis. |
|
|
Term
