GRADED A+ BRADLEY UNIVERSITY
Which of the following correctly defines a frameshift mutation?
It involves the insertion or deletion of a nucleotide. Typically in a non-functional peptide
Which of the following is true regarding B-Lactamases?
They are enzymes secreted by bacteria that target the B-Lactam ring fond in penicillin-class
antibiotics
Which is the following is true regarding enveloped viruses?
They get their envelope through the process of "budding off" from the host cell AND they are
weaker so they tend to be transmitted via physical contact
Which of the following is true regarding antigenic shift?
It occurs through reassortment of viral genomes resulting in a large change in spike proteins
Which of the following is true regarding Gram - bacteria?
They have a double membrane, LPS is a component of their cell membrane, and that they are
typically harder to kill than Gram + bacteria
What is the barrier of bacteria?
Bacterial membrane
, Can antibiotics be used against endospores?
No
Which of the following methods of sterilization can be sued on heat-stable materials?
Flaming and the Autoclave
Staphylococcus aureus is placed into varying concentrations of Chloride: 0%, 0.5%, 1%,
2%, 3%. Growth is present in 0%, 0.5%, and 1%. A sample from each of the original solutions
is placed into corresponding containers containing no Chloride. Growth is present in the
corresponding 0%, 0.5%, 1% and 2% containers (remember there is no chloride present in
these containers). Which of the following statements correctly summarizes this data.
The solution is bacterial-static, and MIC: 2% while MBC: 3%
Which of the following is able to kill endospores?
Auto-clave
Bacterial cell 1 has a plasmid that contains genes that encode for Tetracycline and
Amoxicillin resistance. It also contains a chromosomal gene that encodes for Penicillin
resistance. Bacterial cell 1 conjugates with bacterial cell 2, successfully copying +
transferring its plasmid. Which of the following statements is true regarding this scenario.
Bacterial cell 2 is resistant to Amoxicillin and Tetracycline, but not penicillin
Does the direct ELISA text identify antibodies present in a sample?
False, it identifies antigens, and starts with antibodies
Which of the following correctly defines generalized transduction?
