Viruses (2.2)

Classified as Nonliving organization (cells) metabolism responsiveness growth reproduction evolution ecology

Classification

Basic Structure protein capsid genetic material (DNA or RNA)

Host Range most are very specific some can infect many species bacteriophage infects bacteria cells

Viral Reproduction lytic cycle (lysis) lysogeny (dormancy)
