Explain the difference between translational, post-translational, transcriptional, and post-transcriptional gene regulation. Give brief examples of each.
Where does the following regulation happen? •transcriptional regulation •post-transcriptional regulation •post-translational regulation •miRNA/siRNA (mRNA degradation) •Ubiquitination/phosphorylation (protein degradation)
Which of these is NOT a form of post-transcriptional gene regulation? a. Efficiency of ribosomes recognizing translational signals b. Polypeptide stability c. mRNA stability d. Release of the mRNA at termination e. None of these
What is the difference between a transcriptional and a translational start site? A) there is no difference-these terms are interchangeable B) The transcriptional start site is used to initiate the production of the polypeptide while translation start site is used to initiate the production of the initial RNA transcript C) The translational start site is important for determining the half-life of the RNA D) The translational start site is used to initiate the production of the polypeptide while transcriptional start...
