Use the Following Information to Answer the Questions Below

Use the following information to answer the questions below.
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.
-When the Bicoid protein is expressed in Drosophila,the embryo is still syncytial (divisions between cells are not yet fully developed) .This information helps to explain which observation by Nüsslein-Volhard and Wieschaus?

A) mRNA from the egg is translated into the Bicoid protein.
B) Bicoid protein diffuses throughout the embryo in a concentration gradient.
C) Bicoid protein serves as a transcription regulator.
D) Bicoid protein determines the dorsoventral axis of the embryo.
E) Bicoid protein serves as a translational regulator.
