Antibiotics such as tetracycline, streptomycin, and bacitracin aresmall organic molecules that are synthesized by particular speciesof bacteria. Microbiologists have hypothesized that the reason whycertain bacteria make antibiotics is to kill other species that occupythe same environment. Bacteria that produce an antibiotic may beable to kill competing species. This provides more resources forthe antibiotic-producing bacteria. In addition, bacteria that havethe genes necessary for antibiotic biosynthesis contain genes thatconfer resistance to the same antibiotic. For example, tetracyclineis made by the soil bacterium Streptomyces aureofaciens. Besidesthe genes that are needed to make tetracycline, S. aureofaciensalso has genes that confer tetracycline resistance; otherwise, itwould kill itself when it makes tetracycline. In recent years, however,many other species of bacteria that do not synthesize tetracyclinehave acquired the genes that confer tetracycline resistance.For example,…

Microbiologists announced the discovery of over 30 new species of bacteria that thrivebetween the teeth and gums of humans. The bacteria could not be grown in the researchers’ laboratories,nor were any of them ever observed via any kind of microscopy. If they couldn’t culture them or see them,how could the researchers know they had discovered new species? If they couldn’t examine the cells for thepresence of a nucleus, how did they determine that the organisms were prokaryotes and not eukaryotes?
Each species of bacteria has its own distinctive cell surface. Thecharacteristics of the cell surface play an important role in processessuch as conjugation and transduction. For example, certainstrains of E. coli have pili on their cell surface. These pili enableE. coli to conjugate with other E. coli and also enable certain bacteriophages (such as M13) to bind to the surface of the E. coli andgain entry into the cytoplasm. With these ideas in mind, explainwhich forms of genetic transfer (i.e., conjugation, transduction,and transformation) are more likely to occur between different speciesof bacteria. Discuss some of the potential consequences ofinterspecies genetic transfer.
A common step in the isolation of cells from asample of animal tissue is to treat the tissue with trypsin,collagenase, and EDTA. Why is such a treatment nece-ssary, and what does each component accomplish? Andwhy does this treatment not kill the cells?
The Archaea is similar to the Eukarya in the following characteristic except? initiator 1RNA (protein synthesis) O 16S FRNA nucleotide sequence sensitivity to antibiotics types of RNA polymerase The Archaea differ from the Eubacteria in the following characteristic except: * O initiator tRNA (protein synthesis) origin of DNA replication sensitivity to antibiotics types of RNA polymerase

Figure 13.6 Which of the following statements is true? a. Gram-positive bacteria have a single cell wall formed from peptidoglycan. b. Gram-positive bacteria have an outer membrane. c. The cell wall of Gram-negative bacteria is thick, and the cell wall of Gram-positive bacteria is thin. d. Gram-negative bacteria have a cell wall made of peptidoglycan, while Gram-positive bacteria have a cell wall made of phospholipids.

Griffith, in his 1928 experiments, demonstrated thatbacterial strains could be genetically transformed. Theevidence that DNA was the transforming principleresponsible for this phenomenon came later. Whatwas the key experiment that Avery, MacCleod, andMcCarty performed to prove that DNA was responsiblefor the genetic change from rough cells into smoothcells?
