What are some reasons that cultures are important for research? (select all that apply) morphological and phylogenetics studies investigating gene function via gene knockouts discovering novel antibiotics cultures are unnecessary, only DNA is important depositing in culture collections for future research

Why is Axenic growth of microorganism in the laboratory important to the study of microbiology and characterization of microbes? Group of answer choices To interpret the results of biochemical tests To practice good aseptic technique To comply with local, state, and federal regulations To allow microbes to grow without competition or predation To prevent the formation of biofilms

Part A - Surveying microbial diversity In order to develop and refine water treatment systems, as well as other uses of microbes, it is often important to understand what microbes are present. To do this, researchers can use culture-dependent or culture-independent methods. Each of the statements below supports using one or the other of these methods. Place each statement into the bin for the approach that it supports. Drag choices to the correct bins. Prevents risk of missing an unusual species due to lack of appropriate PCR primers. Allows isolation of individual species, not a mixed species assemblage. Provides living microbes for further testing and analysis. Provides living microbes for further testing and analysis. Genetic analysis allows identification of genetic material regardless of growth requirements. Allows the detection of genetic fragments, not just genes from entire organisms. Not all microbes grow in one culture medium; knowing all species may be important. Culture-dependent methods Culture-independent methods
