gradient by mom's gene.
TRUE
What regulate anterior part of embryo

mRNA
How is bicoid made?
Mom and made by nurse cell
How do nurse cell make bicoid?
These nurse cell move into the oocyte and within oocyte, they are
located into anterior part.
What does bicoid muation indicate?
no functional bicoid protein - embryo without head
what makes Tail tip and Abdomen?

importance of bicoid
what does bicoid do?
setting up head structure
