Summary Introduction
To review:
The ability of the linear chromosomes in organisms like Borreliaburgdorferi to avoid degradation.
Introduction:
Borreliaburgdorferi is a Gram-negative pathogenic bacterium that causes the Lyme disease. It has a unique genome as it contains a large linear chromosome, which is 910,725 base pairs long. This chromosome contains a total of 853 genes that encode for DNA (deoxyribonucleic acid) replication, transcription, translation, other transports, and

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) Erythromycin

- Bacterial conjugation has medical consequences. For example, certain plasmids contain genes that code for toxins. The causative agent of a deadly form of food poisoning, E. coli 0157, synthesizes a toxin that causes massive bloody diarrhea and kidney failure. This toxin is now believed to have originated in Shigella, another bacterium that causes dysentery. Similarly, the growing problem of antibiotic resistance is partly attributable to the spread of antibioticresistant genes among bacterial populations. Antibiotic resistance develops because antibiotics are overused in medical practice and in livestock feeds. Suggest a mechanism by which this extensive use promotes antibiotic resistance.arrow_forward1) It is declared that some ribozymes are tightly bound to proteins. What isn't the function of those proteins? Select one: A) Regulate the enzymatic activities of the ribozyme B) Conduct the enzymatic function of the ribozyme C) Help the RNA fold properly D) Stabilize the RNA and the ribozyme 2) What promotes the histone chaperone - CAF-I aggregation to the replication machinery? Select one: A) Nucleosome tall modification B) sliding DNA clamp C) Clamp Loader D) DNA polymerasearrow_forwardDeamination of cytosine to form uracil can happen spontaneously during replication. It can be repaired relatively easily by photoreactivation repair using DNA polymerase I b) base excision repair using DNA glycosylase creating an AP site c) base excision repair using topoisomerase creating an AP site d) none of thesearrow_forward
- While there is a T nucleotide in one position in one of the double chains, if there is a G nucleotide opposite this nucleotide in the complementary chain; Does this pose a problem? If you think it will cause a problem, explain what kind of problem it may create. What repair systems might work to fix this problem? Briefly describe the operation of these systems.arrow_forwardWhat are degenerativediseases?arrow_forwardIn a process of production of a recombinant protein by E. coli cells, it was observed accumulation of acetate in the culture medium. In this situation, it can be said that: (a) certainly the process in question was being conducted in anaerobiosis (B).Acetate accumulation is advantageous for the process as the acetate formation reaction generates 1 molecule of ATP (c)Knowing that decreasing the temperature of the process causes a reduction in the rate of glycolysis, this could be a strategy to reduce the accumulation of acetate (d).the acetate formed can be re-assimilated by the cell if the glyoxylate pathway is activated at some point in the culturearrow_forward
- Usually, bacteria only make tryptophan when tryptophan is absent or available in low concentration. However, a particular bacterial mutation makes tryptophan all the time whether or not tryptophan is present. What could explain this phenotype? A) the terminator hairpin is unable to form B) the antiterminator hairpin is unable to form C) trpE is mutated D) trpD is mutated E) trpA is mutatedarrow_forwardFor each of the following ( A & B ) provide the method of transfer and a brief explanation as to why the method would not take place under the conditions described . 1. Which method of DNA transfer between bacteria would not take place if the donor and recipient were separated by a filter with a pore size of 0.45 um or another physical barrier 2. Which method of transfer would be blocked by the presence of high concentrations of DNAase ( enzymes capable of degrading DNA ) ?arrow_forwardWhich of the following is NOT correct concerning the initiation of replication in E. coli? Question 29 options: A) It involves a region of the DNA called oriC. B) DnaA proteins bind to the DNA to begin separation of the strands. C) The strands are initially separated at GC-rich regions of DNA. D) Following initial separation, enzymes continue to separate the parental DNA strands around the rest of the chromosome.arrow_forward
