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 WebOct 7, 2010 · Syncytial Specification (in Drosophila) • Characteristic of most insects where early nuclei share cytoplasm • Specification by interactions between cytoplasmic morphogens • Variable cleavage produce no rigid cell fate for specific nuclei • After cellularization, conditional development usually occurs 3.11
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… WebOct 26, 2024 · Also referred to as cell differentiation, cell specialization is the process wherein “ general ” or “ common ” cells evolve to form specific cells that have specific functions.
