A scientist studies the production of a key digestive enzyme in silk moths. The moths have one gene for this enzyme, and the scientist extracts mRNA transcribed from this gene as well as protein translated from it. The gene has three introns in its sequence.Question 1Use the passage to answer the question.Part A: If the researcher compares mRNA from inside the nucleus to mRNA from the ribosomes, what will be found?(1 point)Responsesless mRNA in the nucleusless mRNA in the nucleusshorter mRNA in the ribosomesshorter mRNA in the ribosomesidentical mRNAs in both placesidentical mRNAs in both placesmRNA covalently attached to protein in the nucleusmRNA covalently attached to protein in the nucleusQuestion 2Part B: Use the passage to answer the question.If the same scientist extracts the DNA for this gene and finds that it becomes methylated over the life of the organism, how will digestion change over time?(1 point)ResponsesIt will occur at lower pH.It will occur at lower pH.It will rely more on this enzyme over time.It will rely more on this enzyme over time.It will use methylated copies of the enzyme.It will use methylated copies of the enzyme.It will involve a lesser quantity of this enzyme over time.It will involve a lesser quantity of this enzyme over time.Skip to navigation
Question 1:
Identical mRNAs in both places
Question 2:
It will rely more on this enzyme over time.
