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.
â¢ In eukaryotes, multiple replication sites are present in a single DNA molecule whereas, in prokaryotes, a single replication site is present in the circular DNA molecule. â¢ In prokaryotes, DNA replication involves three polymerase enzymes; namely, DNA polymerase I, DNA polymerase II, and DNA polymerase III.rokaryotic DNA and eukaryotic DNA vary widely; so do their replication processes. Prokaryotic DNA Replication. Unlike in eukaryotes, there is a single circular DNA exists in prokaryotes. The replication in the prokaryotic chromosome begins at the origin of replication.
