Step by step
Solved in 2 steps
- What would happen to a bacteria that lost a plasmid for antibiotic resistance? Would it still be able to grow in normal growth conditions? Explain.Describe ,A Hfr bacterium mates with an F- plasmid containing bacterium. What will be the type of bacteria after conjugation is complete?Why is it important to know if the bacteria is encapsulated or not?
- When T4 phage isolated from E. coli strain B infect E. coli strain K, what will be the EOP (efficient of plating)? Explain why. Fe VThe ribosome is the target for many important antibiotics. These drugs must discriminate between bacterial and eukaryotic ribosomes to achieve drug specificity and toxicity. For the two common antibiotics below, what is their mechanism of action and why are they more toxic to bacteria than eukaryotes? a) Tetracycline b) ErythromycinLysozyme and the antibiotic penicillin have similar mechanisms of action in that they both cause damage to the bacterial: Question 5 options: A) cell membrane. B) capsule. C) cell wall. D) DNA.
- Which of the statements is TRUE about conjugation? a) Plasmid DNA is transferred from a donor (F+) cell b) It may only be performed by competent cells c) DNA is always integrated into recipient chromosome d) It may be specialized or generalizedWhich Part Of The Bacteria Actually Gets Stained?The wild type bacterium is lac+ amps, leu+, ade+ Mutant I is: lac+ amp r, leu-, ade+ Mutant 2 is: lac+, amp s, leu+, ade- Mutant 3 is: lac-, amp r. leu-, ade- The circles below represent six different types of growth medium for these cells. The text below each circle indicates the composition of the medium in that plate. Please divide each plate into quadrants, one for the wild type and one each for the three mutants. Then, draw in the appearance of the plates after we place cells of these genotypes on them and allow growth to occur (if it can). rich, glucose rich, lactose OO minimal, leucine, adenine minimal, glucose, adenine rich, lactose, amp O minimal. glucose, leucine
- If the generation time of Escherichia coli is 30 minutes, starting with 4 E. coli cells, how many cells can you obtain after 2 hours of growth? A: cellsAn F' merozygote is formed as a result of the following events: 1) the recipient cell receives genes which used to be a part of an Hfr bacterium chromosome 2) an F' bacterium excuses an F factor from another bacterium chromosome 3) an F factor that was imprecisely excised from Hfr chromosome was transferred to an F- bacterium 4)an F' bacterium conjugate with an F- bacterium 5) an F' bacterium incorporates an F factor into its chromosome 6) an F- bacterium incorporates an F factor into its chromosomeIn a petri dish with solidified agar with escherichia coli, enterobacter aerogenes and staphylococcus aureus, you streak a loopfull of lytic T4-phage in a single line onto the center of the the dish, how do you know if bacteriophage infected the bacteria. why didn't the bacteriophage infect all 3 bacteria?
