Describe the process of fertilization including the acrosomal and cortical reactions, ZP proteins and cell signaling. (100 words or less)
Describe the process of fertilization including the acrosomal and cortical reactions, ZP proteins and cell signaling....
1. Detail the events associated with fertilization in sea urchins. Include the acrosomal/cortical reactions and how polyspermy is prevented. 2. Describe the processes of cleavage, gastrulation, and neurulation in frogs.
Describe conception, including sperm capacitation, acrosomal reaction, sperm penetration, cortical reaction, and fusion of pronuclei.
5.DISEASE AND PATHWAYS: Most drugs target proteins involved in signaling pathways in the cell. Describe two examples by which a protein can be chemically altered and thereby act as a logic switch in a signaling pathway in the cell. 6.MOLECULAR DRUG DOCKING: Why is molecular docking (e.g. autodock vina) take less time to run than molecular dynamics? What aspect of molecular reality regarding the target protein is sacrificed during simulation to obtain computational speed?
-Trace the general mechanism by which a signal transduction pathway occurs (i.e. from signaling molecule to response) Describe the two ways in which signaling proteins act as molecular switches -Which amino acid residues do kinases typically add phosphate groups? Distinguish between the two types of G proteins -What proteins regulate GTP-binding protein (G proteins) in terms of activation and inactivation? - Distinguish between the three main classes of cell surface receptors.
-Trace the general mechanism by which a signal transduction...
describe the process of DNA replication in detail, including the names and functions of all proteins involve
Describe the process by which a cell would display an intracellular (virus) on MHC, including how the pathogen gets in the cell and eventually gets placed on the correct MHC (tell me the class) and displayed on the cell surface.
Name: 2. You cell cycle. Describe this process, including DNA replication (when is occurs and what is produced), The major portions of the cell cycle and what those portions are divided into. For the cell division process you should use a chromosome number of 2N-4, instead of the real human chromosome number of 2N-46 have a broken leg and you realize that in order to heal your body needs to proceed through the
Name: 2. You cell cycle. Describe this...
Cell death (apoptosis) is a structured and organized process. Describe why the process of shrinking and fragmenting virally infected cells, as opposed to breaking open the cell membrane to cause death, is beneficial to the rest of the body. Predict reactions to the arrest of apoptosis within in an organism. Justify your answers with examples.
2. Describe the process of obtaining energy (light-dependent reactions) and the process of using that energy for carbon fixation (light-independent reactions) in photosynthesis. Make sure to mention where in the cell each of these reaction types are occurring and what the chemical inputs and outputs are for each of those processes.
describe in your own words process of transcription and translation. No less than 100 words
