Gram +

Answer 17

Purple, thick peptidoglycan/lipoteichoic acid cell wall

Question 18

Gram -

Answer 18

pink-red, thin peptidoglycan cell wall and an outer membrane

Question 19

Eukaryote

Answer 19

ETC in mitochondria
Large ribosomes
Reproduce vs mitosis

Question 20

Prokaryote

Answer 20

ETC in cell membrane
Small ribosomes
Reproduce via binary fission
Plasmids carry DNA material. May have virulence factors. Plasmids that integrate into genome are Episomes

Bacteriophage

Answer 42

bacteria virus. Tail sheath injects DNA/RNA

Question 43

Viral Genome

Answer 43

May be DNA or RNA. Single or double stranded

Question 44

Positive Sense

Answer 44

can be translated by host cell

Question 45

Negative Sense

Answer 45

RNA replicase must synthesize a complimentary strand, which can then be translated

Question 46

Retrovirus

Answer 46

single stranded RNA. Reverse transcriptase needed to make DNA

Question 47

Lytic Cycle

Answer 47

virions made until cell lyses

Question 48

Lysogenic Cycle

Answer 48

virus integrates into genome as provirus or prophage. Goes dormant until stress activates it.
