The three possible methods of genetic recombination are...
Transformation, translation, conjugation
Conjugation, transformation, transduction
Transduction, transformation, translation
Reflection, translation, conjugation
Which genetic material could be transmitted naturally by all three methods (transformation, conjugation & transaction) of horizontal gene transfer?
an E coli chromosome
the genome of a microbe
drug resistance genes
a and c
bacteriophages (bacterial viruses) participate in this gene transfer
transformation
conjugation
transduction
translation
Drug-resistance genes could be transferred by which of the following mechanisms:
conjugation
bacteriophages
Transformation
a, b, and c
Transformation is the transfer of DNA from a donor to a recipient cell
A) by a bacteriophage.
B) as naked DNA in solution.
C) by cell-to-cell contact.
D) by crossing over.
The rate that bacteria develop antibiotic resistance at can be sped up by:
Exposure to lower levels of antimicrobials than prescribed
2.Exposure to broad-spectrum antibiotics (which aren’t specific to a microbe)
3.Overuse of antibiotics in foods/agriculture
4. All of the above
Examples of antibiotics:
Penicillin
Tetracyclines
Neomycin
All of the above
Broad spectrum antibiotics are bad because:
They kill many different pathogenic bacteria
They are really cheap to buy
They can increase the rate of development of antibiotic resistance
All of the above
Antibiotic resistant bacteria are a problem because:
It is more difficult to treat people infected with them
bacteria smell pretty bad
viruses them grow out of control
they are not a problem, I love being sick
The following organisms can be killed by antibiotics
Viruses
Fungi
Protists
Bacteria
Which of the following is a strain of antibiotic resistant bacteria?
RSPCA
NRA
MRSA
GCSE
What can we do to reduce the rate of development of antibiotic resistant strains of bacteria. Choose all that apply.
Always finish a course of antibiotics
Only take antibiotics when they are really needed
Take antibiotics whenever it is possible
Reduce the amount of antibiotics given to animals in the farming industry
Broad spectrum antibiotics are good because:
They Kill many different pathogenic bacteria
They are really cheap to buy
They cause antibiotic resistance
None of the above
Which bacteria pictured is harder to fight and why?
Gram negative bacteria, because it has an extra layer of cell membrane.
Gram positive bacteria because it has a thicker cell wall.
Gram negative bacteria, because it does less cell functions than gram positive bacteria.
Gram positive bacteria, because it does less cell functions than gram negative bacteria.
Which bacteria below would be called “Staphylococcus”?
A
B
C
D
Inflammation....
Is caused by too many white blood cells in one affected area
Can be shown by pus
Is the body's response to infection
Arises when a pathogen leaves the body
Which prevention method listed below kills pathogens entering the digestive system?
Acid in the stomach
Skin
Vomiting
Diarrhea
What is able to be transferred between bacteria during conjugation? Choose all that apply.
Plasmid
Chromosome
What organelle is used in the process of conjugation?
Cell wall
Capsule
Flagella
Pilus
