There are three basic types of secondary messenger molecules: [citation needed] Hydrophobic molecules: water-insoluble molecules such as diacylglycerol, and phosphatidylinositols, which are membrane-associated and diffuse from the plasma membrane into the intermembrane space where they can reach and regulate membrane-associated effector proteins.
There will be 3 quantitative sources followed by a few questions. Section II (Free Response): The number of questions will decrease from 8 questions to 4 questions. The time will also decrease from 100 minutes to 90 minutes. It will continue to be worth 50% of the total exam score. Question 1: Conceptual Analysis; Question 2: Quantitative Analysis
Figure 1: A bi-phasic bacterial growth curve.. A growth curve is an empirical model of the evolution of a quantity over time. Growth curves are widely used in biology for quantities such as population size or biomass (in population ecology and demography, for population growth analysis), individual body height or biomass (in physiology, for growth analysis of individuals).
CpG is shorthand for 5'—C—phosphate—G—3' , that is, cytosine and guanine separated by only one phosphate group; phosphate links any two nucleosides together in DNA. . The CpG notation is used to distinguish this single-stranded linear sequence from the CG base-pairing of cytosine and guanine for double-stranded sequenc
