Binds and inhibits hunchback
nanos deficient mutant: no abdomen
anchored by staufen and oskar
both anterior and posterior
Torso is a RTK.... represses groucho
tailless and huckbein mRNA in association with torso
torso deficient mutant: no telson and acron
both inhibit eachother in synctium blastoderm
establishes polarity which gives rise to segments because of the morphogen gradients made
what controls fine tuning of each segments?
modularity of enhancer regions of each gene
comboniations of enahncers determines which stripe its in
posterior of each parasegment has no expression
regulation at each parasegment regulates where fuhi tarazu is found
what type of regulation occurs between adjacent parasegment border cells with engrailed and wingless?
homeotic genes that give rise to structures in the order of the genes on the chromosome (5' to 3') as anterior-posterior
dont know why
can express legs as antennae
