Microbiology

Front 1

What is Genome?

Back 1

The sum total of the genetic material in an organism

Front 2

What is Chromosome?

Back 2

Genetic info that the microbe must have to survive

Front 3

What is Gene?

Back 3

fundamental unit of heredity responsible for producing protein

Front 4

What is DNA and RNA composed of?

Back 4

Nucleotides

Front 5

What are Nucleotides in DNA composed of?

Back 5

sugar = deoxyribose

phosphate group

Nitrogen base = Adenine, Guanine, Cytosine, Thymene

Front 6

What are Nucleotides in RNA composed of?

Back 6

Sugar= Ribose

Phosphate Group

Nitrogen Bases = Adenine, Guanine, Cytosine, Uracil

Front 7

DNA is always replicated how?

Back 7

Semiconservatively

Front 8

Steps of Bacterial DNA replication?

Back 8

1. two strands of parent DNA separate to open circle

2. RNA primer added by PRIMASE

3. 2 DNA molecules attach at initiation site and begin to add DNA mucleotide to RNA primer

4. DNA polymerase synthesizes 2 strands of DNA

5. 2 daughter molecules separate

Front 9

Example of Highest resistance?

Back 9

bacterial endospore (hardest to kill)

Front 10

Example of moderate resistance?

Back 10

protozoan cysts; some fungal sexual spores; some viruses

Front 11

Example of Least resistance?

Back 11

most bacterial vegetative cells; ordinary fungal spores and hyphae; enveloped viruses; yeasts; and trophozoites

Front 12

Define Sterilization:

Back 12

a process that destroys or removes all viable microorganisms

Front 13

Define bactericide:

Back 13

a chemical that destroys bacteria; except endospores

Front 14

Define Fungicide:

Back 14

chemical that destroys fungal spores, hyphae, and yeasts

Front 15

Define Virucide:

Back 15

chemical that destroys or inactivates viruses

Front 16

Define Sporicide:

Back 16

chemical that destroys endospores

Front 17

Define Bacteriostatic:

Back 17

agent that prevent the growth of bacterial

Front 18

Define Fungistatic:

Back 18

agent that prevents growth of fungi

Front 19

Define Germicide:

Back 19

any chemical that kills pathogenic microorganisms (used on nonliving material or living tissue)

Front 20

Define Disinfection:

Back 20

refers to the use of a physical process or a chemical agent that destroys vegetative cells but do not endosporres (used on inanimate objects)

Front 21

Define Antiseptics:

Back 21

chemicals applied to directly to exposed body surfaces to inhibit vegetative pathogens (used on animate objects)

Front 22

What is Microbial Death?

Back 22

considered to be a permanent loss of reproductive capability
