3. How can a bacteria accumulate multiple resistance genes from other bacteria _________________?
Homework Answers
Ans.
- Many bacterial strains are resistant to multiple antibiotics.
- When a single bacterium develops resistance to multiple antibiotics, then it is known as multidrug-resistant bacteria.
- Many different type of resistant genes may be present in the bacteria, each one of them imparting resistance against a particular antibiotic.
- A bacteria can often accumulate multiple resistance genes from other bacteria through plasmids.
- Plasmid are small pieces of DNA on which accumulation of several resistance genes can take place.
- These plasmids can be transferred among bacterias in a single occurrence.
- Prevalence of these multi-drug resistant bacterias are increasing at an alarming level due to misuse of antibiotics.
- Treatment of these multidrug resistant bacteria is difficult due to availability of fewer or no antibiotic options.

Neisseria has acquired resistance to penicillin. How can it achieve this? A) Neisseria bacteria are dormant and penicillin works on active cells B) Neisseria bacteria are too small for penicillin to kill C) Neisseria bacteria are constantly changing for penicillin to work D) Neisseria bacteria produces proteins to make penicillin ineffective

3. What are two ways by which bacteria can overcome (or resist) the effects of antibiotics (i.e., what are 2 things bacteria can do to antibiotics so they do NOT work against bactertia)? Which form of DNA is most likely to contain genes that specify antibiotic resistance? 4. Some bacteria can stop the activation of complement. Suggest how this might be accomplished (ie- suggest 2 or 3 things bacteria might do to complement to stop or prevent complement activation). Describe...

Bacteria and Drug Resistance If you don't take all your antibiotics when you are sick, you could be creating super drug resistant bacteria. Create a Bacteria class and run some simulations of results. Classes You will have to implement a couple of classes in this creating the classes with methods as given will help quite a bit when it comes to finishing up this program. The methods given here have to be implemented as given, however, you...

True and False A. Multiple independently assorting genes and their alleles can interact to control one train. B. A single gene and its alleles interact to yield modified mendelian phenotypic ratios C. Novel phenotypes may be produced as a result of the interaction of multiple genes D. Gene interaction ultimately results from the interaction of gene products.
