How can we use fungi in biotechnology to save our World or decrease pollution?

A new disease is discovered that causes affected individuals to stumble, appear to have decomposing skin, and have the strong desire to bite another person. One scientist believes a type of fungus to be the cause. What should she do to demonstrate a link between the suspected pathogen and the disease? A. Use PCR to determine what genes are in the fungus B. Calculate the ID50 of the fungus C. Show that the fungus is present in diseased but not healthy individuals, culture it, infect an animal model with it, and reculture the fungus from the animal D. Test affected individuals for antibodies to the fungus

Can I have a backgound on the Endosymbiotic theory and evidence.  Thank you so much!

Why is fluorescent in situ hybridization (FISH) a useful tool for identifying micrboes?   DNA is run over a chip, allowing many different gene to be tested     Different probes can show spatial relationships in the cell with other bound probes     None of the other choices     Probes run across a membrane is a natural follow-up to gel electrophoresis     Provides very detailed information about the genetic sequence of the organism
