Answer In the true bacteria this is an essential component of the cell wall Question What is peptidoglycan? Answer An antibiotic that interferes with the crosslinking of the bacterial cell wall Question What is penicillin? Answer A gelatinous substance that provides cells with additional protection from host immune responses Question What is the capsule? Answer These are resistant cells that are formed by some bacteria and are capable of surviving harsh adverse condition. Question What are Endospores? Answer • Bacteria that break down organic material and have a role in digesting sewage and oil Question What are decomposers? Double JE0PARDY • How much do you wish to wager? Double JEOPARDY Answer A class of mutants that requires the presence of specific organic nutrients for their growth Double JEOPARDY Question What are auxotrophs? Answer A term used to describe materials that are inert to decomposition by microorganisms Question What is non-biodegradable? Answer The process that takes nitrogen gas (N2) and assimilates it into organic material Question • What is nitrogen fixation? Answer These are organisms that will use oxygen but can use fermentation in its absence Question What are facultative anaerobes? Answer Domain that contains all of the “extremophiles” Question What are the Archaea? Answer Molecule used as the gold standard for the identification and classification of all living organisms Question What is SSU*-rRNA? ssu-rRNA - small subunit ribosomal RNA. In prokaryotes this is the 16s RNA Answer Free living symbionts that are found in the roots of leguminous plants Question What is Rhizobium? Answer Intracellular parasites that is the most common cause of blindness in the world and also causes nongonococcal urethritis, the most common sexually transmitted disease (STD) in the United States Question What is Chlamydia? Answer A group of prokaryotes that might have undergone endo-symbiotic events leading to the chloroplasts Question What are the cyanobacteria? Answer A soluble protein excreted by a microorganism that can cause damage to the host by destroying cells or disrupting normal cellular metabolism Question • What is an exotoxin? Answer Four criteria which are used to connect a pathogen with a specific disease Question • What are Koch’s postulates? Answer A disease that is only caused by a certain bacteria when it is carrying a bacteriophage Question What is Diptheria? Answer The organism that causes anthrax Question What is Bacillus anthracis? Answer Organisms usually associated with individuals which become pathogens when the host’s immune system fails Question What are opportunists? Answer Term that refers to the uptake of naked DNA Question What is transformation? Answer The mechanism by which foreign DNA integrates into or exchanges parts with a host chromosome Question What is homologous recombination? Answer A viral infection that results in the production of a prophage Question What is a lysogen? Answer The transfer of genetic material between bacteria through direct cell-tocell contact Question What is conjugation? Answer Term used to describe a plasmid or phage that integrates into the host chromosome Question What is an Episome?
