In development of an embryonic axis of Drosophila, segregation of cytoplasmic components is important. Which axis is determined in this way, what are the cytoplasmic components that are segregated, and where do they go? During L/R axis formation in the Drosophila, oskar mRNA is transported to the posterior pole while nanos mRNA is transported to the dorsal. During A/P axis formation in the Drosophila, bicoid mRNA is transported to the anterior pole while nanos mRNA is transported to the posterior. During A/P axis formation in Drosophila, hunchback mRNA is transported to the anterior pole while caudal mRNA is transported to the posterior. During A/P axis formation in the Drosophila, bicoid mRNA is transported to the anterior pole while coudal mRNA is transported to the posterior..
