Question
Chapter 23, Problem 3PDQ
Summary Introduction
To determine: The difference between differentiation and determination.
Introduction: During the developmental process, cell cells achieve a variety of structural and function specializations, which results in differential gene expression. Developmental processes are controlled by the cascade of gene expression.
Summary Introduction
To determine: The one process that takes place during development.
Introduction: The embryonic development begins after the fertilization of an egg by sperms. During the initial stages, zygote starts mitotic divisions and divides up to the 32-celled stage, which is called blastula. After that, the membranes and tissues start developing.

- What statement best describes the difference between "fate maps" and "specification"? If cells are transplanted from their normal region in an embryo to a different region in a recipient embryo, such cells will alter their fate, but not their specification. Cell fate map describes the allocation of cells to the germ layers, ectoderm, mesoderm, or endoderm, whereas specification describes the exact tissues that each cell will ultimately become. The fate map of an embryo does not change during development -- the fate map of an egg is the same as the fate map of a late blastula -- whereas the specification map of an embryo changes continually as the embryo's development proceeds. The fate map of a cell is determined by labelling that cell and following it during normal development, whereas the specification state of a cell is determined by culturing a cell in an artificial medium and observing what tissues form from it.arrow_forwardWhat is true of the Progress Zone model? a) the length of time a cell resides in the progress zone dictates its identity along the proximodistal axis b) it is consistent with the outcome of removing the AER at successively later stages of limb development c) once a cell leaves the progress zone, its identity is established along the proximodistal axis d) cells of the progress zone are stimulated to divide by the AER e) all of the above You isolate a new mutant chicken strain in which limb outgrowth is severely curtailed. Limbdevelopment begins and the AER initially forms, but the AER then degenerates and subsequent development of the limb is aborted.
