You are studying a signal transduction pathway. Activation of your pathway results in activation of transcription of a gene that you are studying. In addition, activation of the signal transduction pathway results in phosphorylation of a number of effector proteins. Which of the following is most likely an effector protein of your signal transduction pathway that regulates transcription of your gene?
A. An activator protein
B. A coactivator protein
C. A HAT
D. A basal factor
E. RNAPII

2. You discover a signal transduction pathway that regulates actin polymerization. SigC is the ligand, which binds to and activates a receptor tyrosine kinase (RTK). Activation of the RTK leads to the activation of the Ras protein, which then activates the protein kinase PK1 that phosphorylates the RingA protein on S34. When SigC plasma membrane phosphorylated, RingA binds EXTRACELLULAR to the gene regulatory SPACE inactive Ras protein activated Ras protein protein, AP1....

Which of the following statements concerning signal transduction by the insulin receptor is NOT correct? A. The insulin receptor substrate protein IRS-1 in its phosphorylated form activates other proteins. B. The pathway for insulin-stimulated transcription of specific genes involves the protein Ras. C. The insulin receptor phosphorylates itself in the activation process. D. Insulin stimulation of the insulin receptor initiates a cascade of events causing activation of glycogen synthase. E. The receptor protein kinase activity is specific for serine residues...

7. You have identified three fractions, A, B and C that
contribute to transcription of your favorite gene. Your initial
experiments suggest that each fraction contains either an activator
of transcription or a co-activator. You perform a band shift
experiment on different combinations of your fractions and obtain
the data in the image below.
Which of your fraction(s) most likely contain an activator
protein and which most likely contain a coactivator?
A. A most likely contains an activator, and B...

Drosopholia eye development is an example of cell differentiation directed by signal binding to a receptor tyrosine kinase (RTK). In this pathway, R7 photoreceptor development requires a receptor (SEV, sevenless), which is activated by binding to a plasma membrane bound signal (BOSS, bride-of-sevenless) displayed on the adjacent R8 cell Receptor activation leads to activation of RAS via two proteins, Drk (down- stream of receptor kinases) and Sos (son-of-sevenless). Activated RAS leads to activation of a phosphorylation cascade that activates the...

1-1. You wish to insert a gene involved in the degradation of a toxic compound into a plasmid, and then use the plasmid as a vector to transform a species of bacteria so that it can be used in a bioremediation effort to clean up hazardous waste. In order to accomplish this, you will need to ______. SELECT ALL THAT APPLY. -digest both the gene and plasmid with the same restriction enzymes in order to yield appropriate "sticky ends" that...
