Document Summary
If transplant to another embryo will form neural tissues. 2: red band forms mesoderm, if take ac and vp, and put them together, will stell get signalling and form mesoderm (wont get any patterning, pcr for mesodermal genes. If take late state change embryo that has a heart, will have the gene (cardiac actin). Wont have any in ac, wont have them in vp. However if u put ac and vp together, may get cadiac actin (induced the right type of actin) 3: organizer is responsible for 1o embryonic inductuion, 4 function, make something called the prechordal plate self determing, forms this all by itself, starts off as ring of mesoderm. The closer u are to them, the more dorsal character you are. Its whats maing somites dorsal: makes ectoderm near it neural, because of signalling, intiates gastrulation. Centriole is mtoc allows mt to polmerate away from sperm that just came in: provides track, when it rotates, cytoplasm floats around.
