Lytic cycle
What is a cycle that invades a host cell, produces new viruses, and ruptures the host cell when releasing newly formed viruses?
300
cytoplasm or organelles
What is viruses that are acellular and do not contain what two things?
300
How viruses first recongnize a host cell before they can infect it
What is the "lock-and-key" fit?
300
A virus that gradually destroys an infected person's immune system

Illnesses caused by new or reappearing infectious agents that typically exist in animal populations.
What is emerging diseases?
400
ineffective against viral diseases
What is antibiotics?
400
The specialized part of the bacteriophage that allows it to attach to the susceptible bacterium.
What is tail fibers?
500
whether they have RNA or DNA, if their genome is single stranded or double stranded, and linear or circular
What is the six things that classify a virus?
500
it contains a hexogonal head that is filled with DNA, whcih is connected to the sheath by the collar, and has a tail with tail fibers
What is the structure of a bacteriophage?
500
It uses viral RNA as a template for making a double stranded DNA version of the viral genome
