Would bacteriophage T7 be able to infect your cells?
No, bacteriophage infects prokaryotic cells not human cells
When a phage is floating free in the environment, what protects its DNA from degradation?
A protein capsid protects the phage from degradation (physical barrier that protects viral genome)
When a phage infects a cell and assembles it progeny phage, what happens to the bacterial cell?
The bacterial cell is lysed to release progeny phage
Do ALL phage have dsDNA genomes like human genomes?
No, some phage have ssDNA or RNA genomes
When a temperate phage enters the lysogenic state, what does it do?
It inserts its genome into the bacterial chromosome + copied w/ host DNA
Lysogenic cycle → when instead of lysing cells (which kills the host), the phage integrates into bacterial genome without killing the host
