of a single bacterial cell. Each cell in this colony will
most likely
A) express adaptations unlike those of the other cells
B) synthesize the same proteins and enzymes
C) have a resistance to different antibiotics

Microbiologists have announced the discovery of over 30 new species of bacteria that thrive between the teeth and gums of humans. The bacteria could not be grown in the researcher's laboratories, nor were any of them ever observed via and kind of microscopy.
If they couldn't culture them or see them, how could the researchers know they discovered a new species? If they couldn't examine the cells for the presence of a nucleus, how did they determine that the organisms were prokaryotes and not eukaryotes?

- According to Philip Bell’s viral eukaryogenesis hypothesis, genes for DNA replication, RNA transcription, protein translation, and histone proteins were all provided by: an endosymbiotic gram-negative eubacterium an endosymbiotic archaeobacterium a gram-positive eubacterial host cell a double-stranded DNA virus an archaeobacterial host cellarrow_forwardA patient admitted to the hospital for fever and coughing is diagnosed with an active tuberculosis infection, and is treated with an antibiotic named rifampin. The antibiotics seemed successful, and his subsequent tests for tuberculosis came back negative. However, he was re-admitted to the hospital two months later with similar symptoms, was treated with rifampin again, and died of respiratory failure shortly thereafter. It was concluded that he had been infected with an antibiotic-resistant strain of M. tuberculosis. Does this situation meet the criteria for evolution by natural selection? Briefly explain how each of Darwin’s postulates is met/not met: a. Individuals in a population vary in traits. b. Traits are heritable. c. More offspring are produced than can survive, and only some individuals survive and reproduce. d. Individuals with certain heritable traits are more likely to survive and reproduce than others.arrow_forwardWhat advantage do quorum-sensing systems confer onbacterial cells?arrow_forward
- A bacterium has the following characteristics: I. It adheres to the human intestinal lining using a feature that protects it from phagocytes , bacteriophages, and dehydration. II. It can survive being boiled. III. It contains no plasmids and relatively little peptidoglycan. Which of the following characteristics allows this bacteria to survive in a human who is taking penicillin pills? A. gram-negative cell wall B. peptidoglycan in the cell wall C. lipopolysaccharides in the cytoplasm D. long polypeptides in the cell wallarrow_forwardHow can i explain my answers in depth in microbology for example this question: Assume that there are horizontal gene transfers between two completely different bacterial species. In one case it is a plasmid that is transferred via conjugation, in the other case it is a part of the bacterial chromosome that is transferred via transformation. In which of the two cases is it most likely that the transferred DNA will remain and be able to function in the recipient cells? Explain the biological background to your answer . How do I break down the question so I answer it fullyarrow_forwardWhich among A-D is false regarding growth and/or analysis of a bacterial culture? A) O Fed-batch growth: typically results in an increased yield of cells over that obtained with batch growth B) O Auxotroph: requires addition of specific growth factors in order to grow C) O Prototroph: typically the wild type strain that possesses all the features indicative of the species D) O None of A-D is false; all are true statementsarrow_forward
- In general, why might cell-wall inhibiting antimicrobial drugs be less effective on gram-negative bacteria compared to gram-positive bacteria? The gram-negative bacteria digest these drugs at a much higher rate than gram-positive bacteria. The mutation rate of gram-negative bacteria is much greater than that of gram-positive bacteria. The outer membrane of the gram-negative bacteria inhibits penetration of the drug. The peptidoglycan found in gram-positive bacteria is structurally different from that in gram-negative bacteria. The gram-negative bacteria do not synthesize peptidoglycan.arrow_forwardDescribe two (2) importance of understanding the types and nature of bacteria according totemperature to daily human living.arrow_forwardGram-negative bacteria are surrounded by two membrane bilayers separated by a space termed the periplasm. The periplasm is a multipurpose compartment separate from the cytoplasm. The periplasm has a distinct oxidizing environment that allow certain key protein structural features to be formed. Can you identify an amino acid(s) that would be affected by this oxidizing environment? How would it be affected, and what structural features would be sensitive to this environment? Can you discuss the implications of this from a standpoint of recombinant protein expression?arrow_forward
