Help plz ASAP

1. In Step 1, you see the bacteriophage is injecting something into the bacterial cell. What is it injecting? (1pt) *

3A
3B

Answer 1

1. The bacteriophage is injecting its genetic material into the bacterial cell. The genetic material of the bacteriophage is DNA or RNA that could synthesize the protein needed for the virus replication. This will allow the virus to replicate itself inside the bacteria.


2. This type is called lytic cycle because the outcome of this cycle is the lysis(death) of the bacteria cell. In this phase, the genetic material of the virus will hijack the bacteria body and makes them replicate the virus. The lysis of bacteria allows the new virus to invade other bacteria.

3. Answer:3B
Prophage is a bacteriophage DNA that integrates with bacterial DNA. This will be found in the lysogenic cycle that was started at the 3B picture. In this cycle, the virus becomes dormant and won't replicate itself so the bacteria wouldn't lysis. The virus could become active and change into the lytic cycle if a certain condition met.
