When should you identify root causes? 1  Whenever you are faced with addressing a challenging community problem. 2  When there is support for a solution that does not seem to get at the real causes of the problem. 3  When there is ignorance or denial of why a community problem exists.
There are two basic types of organisms based on cell type: Prokaryotic and Eukaryotic. Prokaryotic cells are divided into the domains Bacteria and Archaea. Eukaryotic cells make up the more familiar Domain Eukarya. Prokaryotes are the smallest forms of life that can live independently. Most prokaryotes are tiny single cells, but some can form larger, multi-celled structures.
All three domains of life use positive regulation, negative regulation, and co-regulation to control gene expression, but there are some differences in the specifics of how these jobs are carried out between prokaryotes and eukaryotes.nother major difference between prokaryotic gene regulation and eukaryotic gene regulation is that the eukaryotic (but not prokaryotic) DNA double helix is organized around proteins called histones which organize the DNA into nucleosomes. This combination of DNA + histones is called chromatin.
