9. Which statement is correct? A) The anterior-posterior axis in the developing fly embryo is determined by receptor-tyrosine kinases bound to the orthogonal ends of the dorso-ventral axis.B) Maternal effect genes are transcription factors that trigger the expression of segmentation genes. C) MyoD is a master translation factor involved in muscle cell differentiation.
D) Gap genes are segmentation genes whose mRNAs are present in the unfertilized egg.
E) The cell lineage in C. elegans is a good model for vertebrate development, as it allows for tracing osteocytes (bone cells) back
