A Researcher Has Arrived at a Method to Prevent Gene

question 29

Multiple Choice

A researcher has arrived at a method to prevent gene expression from Drosophila embryonic genes. The following questions assume that he is using this method.
-The researcher in question measures the amount of new polypeptide production in embryos from 2-8 hours following fertilization and the results show a steady and significant rise in polypeptide concentration over that time. The researcher concludes that

• A) his measurement skills must be faulty.
• B) the results are due to building new cell membranes to compartmentalize dividing nuclei.
• C) the resulting new polypeptides are due to translation of maternal mRNAs.
• D) the new polypeptides were inactive and not measurable until fertilization.
• E) polypeptides were attached to egg membranes until this time.
