Bio Ch 18

Front 1

Host Cell

Back 1

Cell that is infected by a virus, fungus or bacterium.
Eukaryotic cell that contains photosynthetic or nonphotosynthetic endosymbionts.

Front 2

Host Range

Back 2

Number of species and cell types possible to infect.

Front 3

Capsid

Back 3

Virus protein coat that encloses a genome that consists of one or more molecules of nucleic acid.

Front 4

Viral Envelope

Back 4

Structure enclosing viral capsid that consist of a membrane derived from the plasma membrane of the host cell. Embedded with virally encoded spike glycoproteins.

Front 5

Bacteriophages

Back 5

Virus that infects bacteria

Front 6

Phages

Back 6

Virus that infects bacteria

Front 7

Viral Genome

Back 7

Genetic material of a virus

Front 8

Integrase

Back 8

Enzyme sometimes encoded by viruses that catalyzes the integration of the viral genome into the host cell chromosome.

Front 9

Prophage

Back 9

DNA of a phage that has become integrated into a bacterial chromosome.

Front 10

Lysogenic Cycle

Back 10

Growth cycle of a bacteriophage consisting of integration, prophage replication and excision.

Front 11

Reverse Transcription

Back 11

Viral enzyme that catalyzes the synthesis of viral DNA starting with viral RNA as a template.

Front 12

Provirus

Back 12

DNA that has already incorporated into a eukaryotic chromosome.

Front 13

Retroviruses

Back 13

RNA virus that utilizes reverse transcription to produce viral DNA that can be integrated into the host cell genome

Front 14

Lytic Cycle

Back 14

Growth cycle of a bacteriophage in which the production and release of new viruses lyses the host cell

Front 15

Latent

Back 15

Term to describe prophage or provirus that remains inactive for a long time.
