QUESTIONS AND CORRECT ANSWERS
COMPLETE STUDY GUIDE
●● lytic cycle
Answer: results in the destruction of the infected cell and its membrane
and replication occurs separately
●● capside
Answer: outer protein coat of a virus
●● lysogenic cycle
Answer: "A type or phase of the virus life cycle during which the virus
integrates into the host chromosome of the infected cell, often remaining
essentially dormant for some period of time"
●● bacteriophage
Answer: a virus that attacks bacteria
●● bacteria
Answer: a prokaryotic microorganism that are typically a few
micrometers in length and have various shapes
,●● restriction enzyme
Answer: an enzyme that cuts DNA
●● antibiotic resistence
Answer: when an infectious organism is not killed by a drug designed to
eliminate it
●● retrovirus
Answer: virus that have RNA but their host has DNA
●● reverse transcriptase
Answer: an enzyme that converts RNA into DNA
●● prion
Answer: an infectious protein
●● Gram positive bacteria
Answer: bacteria with peptidoglycan in their cell wall
●● Gram negative bacteria
Answer: bacteria with complex cell walls that have more
lipopolysaccharides in their membrane
, ●● capsule
Answer: a protective coating around the cell wall in some bacteria
●● plasmids
Answer: circular DNA in bacteria
●● transformation
Answer: the ability for the cell to change its phenotype by uptaking
foreign DNA from its surroundings
●● transduction
Answer: part of the lysogenic cycle in which the bacteriophage DNA
fuses with the host DNA
●● conjugation
Answer: when bacteria join and exchange DNA through a sex pilus
●● obligate anaerobes
Answer: organisms that are poisoned by O2
●● facultative anaerobes
Answer: organisms that can switch from aerobic to anaerobic respiration
