Which of the following is true about the proteins of these cells? A. The protein for cell A is longer. B. The protein for cell A is shorter. C. Cell A produces more of this protein. D. Cell A produces less of this protein.

If you add a transcription factor that triggers the transcription of mRNA for the protein Pitx in this situation what would happen. Group of answer choices A)All transcription of Pitx is stopped by the transcription factor B)Nothing because the Pitx gene is already being transcribed at the maximum ratea C)Nothing, because the Pitx gene cannot be transcribed in this highly coild state D)The amount of transcription of Pitx is greatly increasedt
