a nonliving particle made up of nucleic acid and a lipid protein coat

capsid

a protein coat

envelope

a bilipid membrane

inserted viral DNA

retroviruses

RNA viruses that contain the enzyme reverse transcriptase

reverse transcriptase

an enzyme that uses RNA as a template to make DNA

bacteriophages

viruses that infect bacteria

virulent

viruses that reproduce only by the lyctic cycle

lysis

when up to 200 new phage particles burst

lysogenic cycle

an infection cycle

temperate virus

a virus who's replication includes the lysogenic cycle

prophage

phage DNA that is integrated into host cell's chromoscific site

vector

an intermediate host that transfers a pathogen or parasite to another origin

protease inhibitor

a class of drugs that uses reverse transcriptase to make DNA

oncogenes

genes that cause cancer by blocking normal controls on cell reproduction

proto-oncogene

when DNA inserts itself into a hosts chromosome

emerging diseases

illnesses that are caused by new or reappearing infectionous agents that typically exist in animals

inactivated virus
