Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Terms can be used once, more than once, or not at all anterior Drosophila eggs are produced with the and axes predetermined by bicoid posterior that control the body axis. bicoid encodes a that induces and nanos are expression of genes such as , which in turn induce the development of structures. nanos anterior-posterior that prevents expression of mRNAs, such as ,that determine fate dorsal High to low gradients of bicoid and nanos determine body axis. bicoid protein is present in high ventral levels at the ;nanos, at the dorsal-ventral homeotic genes coordinate genes maternal effect genes translation inhibitor transcription factor giant hunchbackExplanation / Answer
