Antibiotics & Resistance

Which of the following is NOT a way that a bacterium can acquire antibiotic resistance?

• Acquiring resistance genes from its host's cells

• The bacterial DNA mutates

• Acquiring a resistance gene from the parent cell

• Acquiring a resistance gene from the environment

• Exchanging DNA with another bacterial cell

A microbe that can cause disease is called...

• an antibody

• an antibiotic

• a pathogen

• a colony

Which category of antibiotics will disrupt the process of cell wall synthesis within bacterial cells?

• Beta lactams

• Macrolides

• Fluoroquinolones

• Peptidoglycans

Which category of antibiotics will disrupt the process of protein synthesis within bacterial cells?

• Beta lactams

• Macrolides

• Fluoroquinolones

• Topoisomerases

Overuse or misuse of antibiotics can lead to which of the following...

• humans becoming resistant to antibiotics, so infections are harder to treat

• Viral infections becoming more common and harder to treat

• Antibiotics becoming less effective against certain types of bacteria

• Mutations in human DNA that can lead to resistance

Beta-lactam antibiotics (such as penicillins) would be most effective at treating infection by

• gram-positive bacteria

• gram-negative bacteria

Gram negative bacteria are generally harder to treat with antibiotics because

• they have a thick cell wall which can block antibiotics from entering

• they have an additional outer cell membrane which can regulate what enters the cell

• they produce beta lactamase enzymes which can break down antibiotics

• they have pencillin binding proteins

Which is true about MRSA?

• It is a strain of bacteria that will cause a person to become gram-positive

• It is a form of bacteria that is resistant to all antibiotics

• This type of bactieria has genes that code for proteins that can avoid or break down certain antibiotics

• It is a type of bacteria that makes a person antibiotic resistant

Which are examples of horizontal gene transfer among bacteria?

(Select all that apply)

• binary fission

• transformation

• transduction

• conjugation

• mitosis

A mutation...

(choose all that apply)

• is a change in the DNA sequence

• can result in an altered protein (that has a different shape or can do something new)

• is always harmful to the organism

• is only caused by radiation or chemical toxins

• can occur randomly whenever the DNA is copied
