Question

please help me (make sure the answers are correct please)

An operon is a cluster of genes on a bacterial chromosome that are all involved in the same metabolic pathway Mutations that arise as a result of exposure to a mutagenic chemical are called spontaneous mutations. When an Hfr strain conjugates with an F-strain, the F- strain usually becomes F. A good taxonomic system should never change, no matter what new evolutionary data are discovered 33. The term chromid is used for a piece of bacterial DNA intermediate in size between the chromosome and any plasmid and that contains at least one essential or core gene. As electrons travel along the bacterial electron transport chain, hydrogen lons (H") are pumped from inside the cell into the periplasmic space 35. Using proper taxonomic nomenclature, the genus and species names are always italicized and capitalized, for example Staphylococcus aureus. 36. The difference between a plasmid and a megaplasmid is currently based on size. 37. Phylogenetic studies involving 16S rRNA sequences include signature sequences that have been identified for eubacteria, archaeobacteria, and eukaryotes. Most bacteria can only use a single type of sugar (carbohydrate) as an energy source 39. Needle aspiration is the best way to retrieve samples from a patient's stomach. 40. The pentose phosphate pathway and the Entner-Doudoroff pathway are alternative routes from glucose to pyruvate and provide intermediate compounds that can be used as starting materials for nucleotides and amino acids. The term chromosome refers to the largest replicon in the bacterial genome that contains the majority of the core/essential genes Bacteria may use glycolysis and the pentose phosphate pathway simultaneously Fermentation occurs in microorganisms under conditions of high oxygen concentration Spinal fluid samples can be refrigerated while urine samples cannot 45. While most (>90%) of bacteria have a single large circular chromosome, there are bacteria that have a single linear chromosome and other bacteria that have more than one large circular piece of DNA
