Bacteria And Viruses

Front 1

Vector

Back 1

An intermediate host that transfers a pathogen or a parasite to another organism.

Front 2

Protease inhibitors

Back 2

Make up another class of drugs that block the construction of new viral capsids and thus prevent HIV from replicating inside a human cell.

Front 3

Emerging diseases

Back 3

Illnesses caused by new or reappearing infectious agents that typically exist in animal populations- often in isolated habitats- and can infect humans who interact with these animals.

Front 4

Macrophages

Back 4

Immune system cells

Front 5

Reverse transcriptase inhibitors

Back 5

Make up one claw of drugs that block the transcription of viral RNA into DNA and thus prevent HIV from infecting new human cells.

Front 6

Oncogenes

Back 6

Genes that cause cancer by blocking the normal controls on cell reproduction

Front 7

Proto-oncogene

Back 7

Controls cell growth- usually near this is where DNA inserts itself into a hosts chromosome

Front 8

Inactivated virus

Back 8

Not able to replicate in a host

Front 9

Attenuated virus

Back 9

A weakened form of the virus that cannot cause disease.

Front 10

Viroids

Back 10

The smallest known particles that are able to replicate

Front 11

Prions

Back 11

Infectious protein particles that do not have a genome

Front 12

Bacteriophage

Back 12

Viruses that infect bacteria

Front 13

Virulent

Back 13

Viruses that reproduce only by the lytic cycle

Front 14

Retroviruses

Back 14

Contain enzyme reverse transcriptase and RNA. Ex. HIV

Front 15

Lysogenic

Back 15

Allows viruses to hide in their host cell for days, months, or years.

Front 16

Temperate virus

Back 16

A virus whose replication includes the lysogenic cycle

Front 17

Prophage

Back 17

Phage DNA that is integrated into a specific site of a hosts cells chromosome

Front 18

Provirus

Back 18

The inserted DNA into a host cells chromosome

Front 19

Envelope

Back 19

Viruses bylipid membrane

Front 20

Capsid

Back 20

A protein coat surrounding some viruses

Front 21

Virus

Back 21

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