Many other types of genetic analysis can be used that focus on certain types of genes. One example of this is multilocus sequence typing (MLST), which focuses on examining genes called housekeeping genes. Microbes encode both housekeeping and pathogenic genes in their genome. Drag the examples of genes to the correct bins to indicate whether they are housekeeping genes, pathogenic genes, or eukaryotic signature genes. Place the phrase describing a gene product in the correct bin. ► View Available Hint(s) peptidoglycan synthesis genes Housekeeping genes membrane remodeling genes cytoskeletal genes membrane lipid genes Pathogenic genes endotoxin genes Reset ribosomal genes exotoxin genes Eukaryotic signature genes Helparrow_forwardWhat problem with the six-kingdom classification system was addressed by the three-domain classification system?
