Determination Flashcards
_______
- fate of cells fully committing itself
determination
true or false
during determination, the cell is already starting its program to the commitment of its fate
True
the programming and commitment of the cells to their fates is due to ______
cell interaction
mosaic/determinate and indeterminate/regulative development just differ in ________
time of determination
Mosaic/determinate is evident in
_______ insects
Drosophila, C elegans
Indeterminate/regulative is evident in _______ (animal)
frog
true or false
In mosaic, fate is early determined; it can still change
False (it cannot change)
true or false
in regulative fates can still be changed
True
indeterminate or regulative blastomeres corresponds to the ______ of cells; have a certain window of time
flexibility
during _______, something happens that seals the fate
early gastrula
_________: transferred into another area: will NOT BECOME PART OF THE NEURAL PLATE but PART OF EPIDERMIS
Presumptive Epidermis
determination is a function of turning on of _______
- start the cascade of events downstream
selector or master genes
determination is a function of turning on of selector or master genes
- start the cascade of events _______
downstream
it is used in determination and differentiation
Positional information
it is the usual and specific fate of the cell in the course of normal development and differentiation
-usual if it is allowed to develop normally
Prospective significance (fate)
