What will happen to gene transcription if the signaling molecule (ligand) is absent, but the Ras protein is always bound to GTP and why? a. Gene transcription would decrease because Ras-GTP is the inactive form of the signal transduction protein. b. Gene transcription would not change because the receptor must be activated for signal transduction to occur. c. Gene transcription would increase because the Ras-GTP is the active form of signal transduction protein for cell division. d. Gene transcription would not change because the signal is needed to activate signal transduction for cell division.

Step 1
Ras protein is a small GTPase that acts as a molecular switch in the signal transduction pathway. When activated by a signaling molecule (ligand), Ras binds to GTP and becomes active, triggering a cascade of downstream signaling events that ultimately lead to gene Show more…

A transcriptional repressor that controls the transcription of gene A is not normally active unless bound by an effector molecule X. In a certain cell, the domain of the repressor that binds X is mutated. With all other factors being the same, what effect do you predict on the transcription of gene A? A. The transcription of gene A will not be affected. B. The effect on the transcription of gene A cannot be predicted. C. The transcription of gene A will increase. D. The transcription of gene A will decrease.
When a structural gene is under negative inducible control, what would be the result of a mutation that eliminates the repressor protein? a) The structural gene will be constitutively expressed due to the lack of negative inducible control. b) The transcription of the structural gene will not be affected, as a repressor is not required. c) The mutation will lead to activation of an activator upon the lack of a repressor protein, which will allow the transcription to continue. d) As the transcription will require a repressor protein, the transcription will be turned off. e) More cAMP will be produced in a cell to compensate for the lack of a repressor protein.
