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… WebThis 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 asymmetric cytoplasmic determinants or morphogenetic determinants. Thus, the fate of the cell depends on factors segregated into the cytoplasm during cleavage. sight word next worksheetIn 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. A cell specified … sight word my activity

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.
