Name the three major assumptions made by the "Cell theory". (i) The lipid membrane is composed of lipid molecules. Explain the principle of membrane formation highlighting the role of the physical properties of the lipids. (ii) Comparing dimensions and length scales is often a first step in an analysis. Give an approximate value for the thickness of a lipid bilayer and the linear length of a helical turn of a DNA double helix. A technician wants to amplify DNA from a patient sample. However, the lab is not equipped with a thermocycler. (i) (ii) Name two methods for DNA amplification that can be operated at constant temperature and give their acronyms. Explain these two methods in detail using a schematic and name all necessary components that are required to perform the amplification. Describe the main function of the middle ear. Highlight the role of the ossicles and the tympanic membrane.
