There are three general ways a cell can become specified for a particular fate; they are autonomous specification, conditional specification and syncytial specification. This type of specification results from cell-intrinsic properties; it gives rise to mosaic development. The cell-intrinsic properties arise from a cleavage of a cell with asymmetrically expressed maternal cytoplasmic determinants (proteins, small regulatory RNAs and mRNA). Thus, the fate of the ce… Webonic specification process is in turn inapplicable to syncytially cleaving eggs in which differential genomic function is established prior to the point when there appear the membrane-enclosed cytoplasmic domains that are required for specification by intercellular signalling. These arguments show, in a very general
WebThere are two general modes of germ cell specification . In some animal species, germline identity is continuous and is passed via the oocyte to the primordial germ cells (PGCs), which are formed during early embryogenesis. In such animals, specification of germ cell fate involves segregated cytoplasmic ‘determinants’. WebMay 30, 2001 · Abstract.

WebConditional specification involves the ability of some cells to induce developmental responses (such as changes in cell shape or fate) in other cells and is also called … danmiller anesthesia coupon codeIn terms of developmental commitment, a cell can either be specified or it can be determined. Specification is the first stage in differentiation. A cell that is specified can have its commitment reversed while the determined state is irreversible. There are two main types of specification: autonomous and conditional. A cell specified autonomously will develop into a specific fate based upon cytoplasmic determinants with no regard to the environment the cell is in.
