| How much were you paid in your last job? http://apartheidweek.org/top-dissertation-writing-services/ write my paper homework To get around the difficulty of growing most microbes in the lab, recent efforts have focused on conducting surveys based on sequencing marker or 16S ribosomal RNA genes that are conserved across microbial lineages because of their essential role as "housekeeping" genes -- critical for the organism's survival. Genome sequencing of the rest of the genomes of most of these lineages is however proceeding much more slowly. "Microbial genome representation in the databases is quite skewed," said Chris Rinke, DOE JGI postdoctoral fellow and first author of the study. "More than three-quarters of all sequenced genomes fall into three taxonomic groups or phyla but there are over 60 phyla we know of." For the majority of them, however, there are no cultivated members available.
