|
1st stage of gastulation in frog
|
formation of bottle cells and dorsal lip of blastophore forms
|
|
|
what are the parts formed during gastulation directily after the formation of the blastophore
|
|
|
|
stage 2 of gastulation in frogs
|
|
|
|
where is the notecord in the 3rd stage of gastulation... and where is the endo meso eco derm.. were is the blastopore and nural plate
|
|
|
|
in the embryo of a chick what direction do they hypoblast travel to form the primitive groove and where is this
|
travel from the posterior to the anterior so from the m-something region to the area opaca and they travel in the region called the area pellucida
|
|
|
what forms at the tip of the primitive groove
|
henson node
|
|
|
what forms the three major parts of a chick the meso endo and ecto derm
|
epiblast travel from the ouside of the embreo to the inside
|
|
|
what are the hypoblast in chick cells
|
only support and are displaced by epiblast
|
|
|
what is the primitive groove
|
inlongated blastopore
|
|
|
name the regions in a fruit fly egg
|
pointy side is the terior the other end is the postieror and the top of the smile is the dorsal and bottom of the smile is ventral
|
|
|
what is localized in the fly egg that has a dramatic effect-- anterior
|
The mRNA is made from the maternal gene during oogenesis.
It is transported to the anterior end of the oocyte and held there by the cytoskeleton (microtubules and microfilaments, and their motors). The mRNA is not translated in the oocyte or the egg. This is a common feature of animal development: the localization of maternal mRNA in inactive form within the egg. |
|
|
the step of formation for flys and frogs before the final cellular blastoderm is formed
|
the syncytial blastoderm
|
|
|
the biocod mrna is why in a fly
|
its in the anterior side- stuck in the microtubles
|
|
|
what does the biocod mrna do
|
it can code for biocod which is heavly concentrated in the anterior side and not in the posterior side
|
|
|
what does the bocod do
|
biocod will initiate transcription of the hunchback
|
