7. For each of the following initiation/elongation factors, how would eukaryotic translation be affected if it were missing? A) eIF2 B) eIF4 C) eEF2
Explain the process of prokaryotic translation initiation, elongation, and termination and Describe the structure and regulation of the lac operon and trp operon
Describe the process of Prokaryotic RNA transcription in molecular detail You must be able to describe the process and order of events in initiation, elongation, and termination. You must describe the catalytic/biological purpose function of the key proteins/elements in elongation -35 and -10 (Pribnow box) Promoters Sigma factors (does not matter which one) RNA Polymerase (including structure and subunits and mechanism) Rho-independent and rho-dependent termination How sequence composition affects promoter function
Describe/draw the three major steps (Initiation, Elongation and Termination) of transcription. In your description be sure to point out significant DNA sequences and proteins involved and describe their role.
2A. Using the figure below, label and describe how Raskets activated (define GEF and GAP in your answer) C -GTP 23. Describe two points at which the signaling of Ras can be dysregulated to allow Ras to be constitutively activated, allowing continuous signaling to downstream effectors. 5 2C. Briefly, Describe one of the following two pathways downstream of activated Ras (PI3K/PTEN or Raf/MEK/ERK), describing how that specific pathway promotes cancer by discussing each schematic P Rat MAP3K 3 PMEKUZ MAP2K...
Describe the steps (Initiation, Elongation and Termination) involved in translation of mRNA to generate a protein, including the all the important molecules involved and how they interact. Diagrams MUST be included in your answer. (Draw on some paper, then photograph and insert the drawing below.) You may add to your answer using bullet points if you find it easier, but make sure they are in the correct order!
What is the “addiction paradox?” Describe several factors (physical, psychological, behavioral, etc.) that might account for the paradox of continued substance use despite problems.
Enzymes 1. Briefly describe three factors that could alter the activity of an enzyme. 2. How do you think the optimal temperature for enzymes found in thermophile bacteria living in hot pools differ from that of the enzymes found in your body? 3. How do you think the optimal pH of enzymes in the stomach compares to the optimal pH for enzymes in blood? 4. Take a look around your house and identify household products that work by means of...
