what gene specifies eye development for humans and flies
Pax6
in humans and insects, does the same gene specify the formation of an eye?
yes, Pax 6
by inserting a human Pax6 gene into a fruitfly leg, what happens
the regulatory switch gene forms a fruitfly eye, not a human eye
as an embryo develops, a ________ system is formed
coordinate system
the _______ gene determines if you’re in the right anterior/posterior place
Hawkes gene
in embryonic development, information is received from info in the ____ and the _____
egg and genome
cells in development become _________ specialized
progressively
2 general ways that daughter cells can differentiate
- asymmetric division(intrinsic), cells are born different,;
- symmetric division(extrinsic), sister cells become different as result of influences acting on them after birth (close range signals)
proper spindle ________ is required for an asymmetric outcome
orientation
localization ofa cell fate determinant in yeast involves RNP particles, _______ and the _____ _________
a motor, actin cytoskeleton
