Cytoplasmic segregation and induction
WebAsymmetric segregation of cellular determinants is based on the asymmetric localization of cytoplasmic molecules (usually proteins or mRNAs) within a cell before it divides. During cell division, one daughter … Web1. Cytoplasmic segregation " A factor (signal) is unequally distributed in the zygote and ends up in some daughter cells but not others " These cytoplasmic determinants are often transcription factors (proteins that bind DNA to control gene expression) 2. Induction " A factor (signal) is produced and secreted by some

WebMay 5, 2000 · Movies were used to examine nuclear migration, cytoplasmic microtubule growth/shrinkage, spindle elongation, and timing of cell cycle events. To induce GFP-Tub1p expression, mid-logarithmic cultures were resuspended in SC-methionine for 2 h. Induction did not alter cell growth based on doubling times in liquid medium. WebThe cytoplasm acts like a poroelastic material consisting of a porous elastic solid meshwork composed of cytoskeleton, organelles, and macromolecules bathed in an interstitial fluid known as the cytosol (Porter and Moses, 1958; Moeendarbary et al., 2013 ).
