- BQuinolones
- CAminoglycosides
3Which group of antimicrobials target ribosomes
- ACarbapenems
- BBeta-lactams
- CAminoglycosides
4The cell wall contributes to [blank_start]shape[blank_end]. These shapes include [blank_start]cocci, bacilli and spirilla[blank_end]
- Ashape
- Bcocci, bacilli and spirilla
5Features external to the bacterial cell wall aids in chemotaxis
- ATrue
- BFalse
6What features are external to the cell wall?
- APeptidoglycan
- BCapsule
- CFlagella
- Dpili
- Elipopolysaccharide layer
7What are the building blocks associated with the cell wall?
- AN-acetylglucosamine and N-acetylmuramic acid
- BN-acetylegalactoseamine and N-acetylmycelium acid
8Gram positive cell wall is [blank_start]20-80nm[blank_end] thick. Whereas the gram negative cell wall is [blank_start]5-10nm[blank_end]
- A20-80nm
- B5-10nm
9[blank_start]Polysaccharides[blank_end] and [blank_start]charged amino acids[blank_end] in the peptidoglycan layer make it [blank_start]highly polar[blank_end], providing the bacterium with thick [blank_start]hydrophilic[blank_end] surface
- APolysaccharides
- Bcharged amino acids
- Chighly polar
- Dhydrophilic
10Gram negative bacteria can be both hydrophilic and hydrophobic
- ATrue
- BFalse
11Gram Positive bacteria's ability to resist staining techniques is attributed to mycolic acids.
- ATrue
- BFalse
12[blank_start]Capsule[blank_end] gives a slimy surface providing protection against [blank_start]phagocytosis[blank_end]
- ACapsule
- Bphagocytosis
13Function of the [blank_start]sex pili[blank_end] is attachment
function of [blank_start]common pili[blank_end] is attachment to host- Asex pili
- Bcommon pili
14The pili
- Arequires interactions between adhesins for attachment
- BInvolved in movement across surfaces
- Cprevents phagocytosis
- Dno immunogenic
15Bacterial genomes are circuar, replication begins at the [blank_start]orign of replication[blank_end]
- Aorign of replication
16H[blank_start]elicases[blank_end] and t[blank_start]opoisomerases[blank_end] unwind and seperate DNA strands
- Aelicases
- Bopoisomerases
17DNA strand serves as a template, generating [blank_start]two replication forks[blank_end] which proceed in the opposite direction around the chromosome
- Atwo replication forks
18[blank_start]Two[blank_end] copies are generated
- ATwo
19Replicated genomes are [blank_start]segregated[blank_end]
[blank_start]Septum[blank_end] forms in the middle of the cell
cell [blank_start]divides[blank_end] to give separate daughter cells- Asegregated
- BSeptum
- Cdivides
