A) on an activated receptor molecule, or (intramolecularly) on the same STAT molecule. B) on a Janus kinase molecule, or (intramolecularly) on the same STAT molecule. on an activated receptor molecule, or on another STAT molecule in a dimer. on a Janus kinase molecule, or on another STAT molecule in a dimer. E) on the same STAT molecule or on another STAT molecule in a dimer.15. Refer to the figure below. Outside of cel Cytokine JAK Phosphorylation Inside of coll Dimerization DNA Nucleus Transcription MRNA The figure shows a signal transduction pathway involving two proteins found in the cytoplasm-JAK and STAT. Based on this figure, what are the roles of JAK and STAT in this pathway? O JAK is a protein kinase and STAT is a G protein. O JAK is a G protein and STAT is a transcription factor. O JAK is a protein kinase and STAT is a transcription factor. JAK is a G protein and STAT is adenylyl cyclase. O JAK is a transcription factor and STAT is a GTPase.Consider the fol lowing 4 statements Stat 1 : Elements a and h of a PDSET (S, g} is always comparable Stat 2 : The PDSEI' {2+ , II is totally ordered Stat 3 :The PDSEI' {HS} , E} does not have a least element Stat 4: 2 is the least element of PDSET [Z] Cheese all the correct choices a} Stat 1 is True and Stat 2 is True b} Stat S is False E] Stat 2 is False cl} Stat 4 is True eIIStat 3 is True and Stat 1 is True 03.
