Flashcards in The Cell Deck (12):
1

Bacterial Teansformation

Integration of foreign genetic material into the host genome, usually this occurs when The contents of lysed cells is picked up by bacteria in that vicinity

2

Bacterial Conjugation

Bacterial form of sexual reproduction, the donor male + unidirectionally gives its genetic material. To have this transfer occur, a sec pili is necessary and is encoded by sex factors. The best studied sex factor is F factor in E. coli. HFR= high frequency of recombination

3

Transduction

Requires a vector, a virus (obligate intracellular pathogens)- aka bacteriophage

4

Transposons

Genetic elements capable of inserting and removing themselves from the genome

5

Phases of bacterial growth

Lag phase, exponential, stationary, and death

6

Are enveloped or non enveloped viruses easier to kill?

Enveloped, they are sensitive to heat, desiccation, detergents

7

Positive sense RNA Virus

Implies that the genome may be directly translated to functional proteins by ribosomes of the host cell, just like mRNA

8

Negative sense RNA viruses

Require synthesis of an RNA strand complimentary to the negative sense RNA STRAND to use as a template for protein synthesis . Negative sense RNA viruses carry RNA replicase in the virion

9

Retroviruses

Enveloped , SS RNA viruses that carry reverse transcriptase . Reverse transcriptase synthesizes DNA from SS RNA. Dna can be integrated into host genome

10

Productive cycle - virus

When virus allows host cell to survive and symbiotic

11

Extrusion

A process by which a virus leaves the cell by fusing with its plasma membrane

12

Three types of recombination in bacteria

Transformation, conjugation, transduction
