EBIO 2070 exam questions and
answers(graded A+)
Transcription factor genes. Determine a cell's function. Intercellular
signaling genes. Cellular communication. - answer Describe the 2 main
types of genes that regulate development
Growth Morphogensis pattering differation - answer Define the 4
processes that drive development
Zygote->Cleavage stage->Blastula->Gastrula->neurulation-
>Organogenesis - answer Describe the major stages of vertebrate
development.
a single cell fertil - answer Zygote
a series of mitoses divide the zygote into a many-celled embryo - answer
Cleavage stage
hollow ball of cells - answer Blastula
An indented blastula, they contain an endoderm, ectoderm, and
mesoderm - answer gastula
formation of the neural tube by invagination at the dorsal - answer
Neurulation
Spina Bifida fix with fluoric acid - answer Neurulation fails
Development of organs and other structures by coordinated growth,
patterning, differentiation, morphogenesis(recycling of main
developmental processes....) - answer Organogenesis
, cells divide - answer Growth
which arethe coordinated movement of embryonic cells to give shape. -
answer morphogenetic movements
Morphogenetic movement in which the indenting of a sheet of cells forms
a groove, tube, or cavity. Driven by changes in cell shape caused by
changes in the cytoskeleton (cell skeleton).Development - answer
Invagination
amoeba-like movement of cells to a new place. Caused bychanging
expression of cell adhesion and cytoskeletal gene - answer Migration
Cell suicide - answer Apoptosis
Invagination->migration->apoptosis - answer Morphogensis order
Sets of embryonic cells in specific parts of the embryo are allocated to
form specific tissues, organs, and structures - answer Patterning:
Embryo->axial patterning->morphogensis+Tissue patterning - answer
Order for patterning
whole regions of the early embryo along the main body axes acquire
specific T.F.s combinations - answer Axial Patterning
individual cells in embryonic regions progressively acquire their own
unique sets of T.F - answer Tissue Patterning
Maternal determinants and morphogenetic gradients - answer Axial
Patterning along dorsal-ventral, anterior-posterior, and left-rightbody axes
is accomplished by two main phenomena;
