1. a ___ mutation occurs if the mRNA codon that results codes for a
stope codon and stops the production of the protein wherever it
occurs nonsense
2. the human whipworm, trichuris trichiura, is transmitted
through____ingestion of contaminated, soil, hands, or food
3. in ____, polypeptides are synthesized using mRNA sequences and
cellular machinery, including ____ molecules. Translation, tRNA
4. The two most common viruses associated with the common cold
are ____ and _____coronaviruses & rhinoviruses
5. A organism that is present as part of our normal microflora cannot
cause an infection will result in a disease condition. False
6. There are multiply ways (portals) for pathogens to enter the body.
Indicate which portals of entry are used for the Urogential tract
system. Sexual contact
7. Clostridium perfringens, a gram-positive, endospore-forming
bacterium, can be implicated in which of the following diseases?
Necrotizing fasciitis, gas gangrene
8. ____is considered the sturdiest of all non-endospore pathogens. It
has traits that allow it to survive high salt, extremes in pH, and
high temperatures straphylococcus aureus
9. Methicillin-resistant staphylococcus aureus (MRSA) is particularly
dangerous because it is ALWAYS more pathogenic than non-
resistant strains of S. aureus false
, 10. Biofilms are particularly troublesome with skin and eye
infections because of all the following charactheristics EXCEPT
biofilms are always composed of a single genus of bacteria
11. The part of the gastrointestinal tract with the largest natural
microbiota is the large intestine or colon
12. ____ causes strep throat, an infection of the pharynx that also
causes high fever and can lead to scarlet fever, acute rheumatic
fever, and acute glomerulonephritis streptococcus pharyngitis
13. ___ commonly known as pinworm, is a common cause of
anal itching in young children enterobius vermicularis
14. The skin is its own defense because of the following sweat is
inhibitory because it has a low pH and high salt content; millions
of epidermal cells slough off everyday taking attached microbes
with them; sebum has a low pH which makes skin inhospitable for
most microbes; lysozyme is found in sweat (and tears and saliva)
and breaks down peptidoglycan a unique component of bacterial
cell walls; skin has antimicrobial substances called antimicrobial
peptides that disrupt membranes of bacteria; keratinized surface
prevents most microbes from penetrating

favorable for the microorganism because of transfer to an
inappropriate body site or weakened immunity in an individual
opportunistic
