Fatty acids from Glycolipids and phospholipids, on the other hand, have two hydrophobic chains that are too bulky to fit into the a spherical shape as micelles do. Thus, they preferred to form glycolipids and phospholipids as lipid bilayers, which are discussed in the next section.
DNA Helicase-The enzyme responsible for separating the two strands of DNA in a helix so that they can be copied during DNA replication. DNA Ligase-The enzyme responsible for sealing together breaks or nicks in a DNA strand. Responsible for patching together Okazaki fragments on the lagging strand during DNA replication.
Extraction of DNA is often an early step in many diagnostic processes used to detect bacteria and viruses in the environment as well as diagnosing disease and genetic disorders. DNA is the precipitated by mixing with cold ethanol or isopropanol and then centrifuging. 2  The DNA is insoluble in the alcohol and will come out of solution, and the alcohol serves as a wash to remove the salt previously added.
