Which proteins are encoded by genes that code for the first mRNAs transcribed in Drosophila embryos?
A)Gap and Pair-rule proteins
B)Dorsal proteins
C)Bicoid and Nanos proteins
D)Caudal and Hunchback proteins
E)Morphogen proteins

Question

The genes that code for the first mRNAs transcribed in Drosophila embryos are bicoid and nanos genes. These genes encode for the bicoid and nanos proteins, which play important roles in establishing the anterior-posterior axis of the developing embryo. The other choices (A, B, D, E) encode for proteins that play roles in other aspects of embryonic development.
