Document Summary
Lipid bilayer that comes from the host cell membrane. The progeny that comes out also have the envelope. Enveloped viruses are more susceptible to drying and chemicals such as disinfectants o. Damaged envelope = no longer infectious: non enveloped = also has spikes but comes out farther. Attachment: virus attaches to host cell via very specific receptors o. Synthesis: nucleic acid, viral proteins, host cell dna degraded, all machinery directed toward viral replication. Assembly: all the parts of the virus come together to make new viral particles. Release: host cell lyses which releases the virus. Number of viral particles released --> burst size (150 viral particles) Prophage: dna of the phage carried by a lysogen o. Can be released from the genome and goes through lytic cycle. As the lawn is growing / cells multipy, the phage infects them --> infect neighboring cells --> 200 phages come out of those --> infect neighboring cells --> etc.
