WebCytokinesis is the process that divides the cytoplasm into two distinctive cells. Interphase G1 Phase The first stage of interphase is called the G1 phase, or first gap, because little change is visible. However, during the G 1 stage, the … WebCell-surface receptors are membrane-anchored proteins that bind to ligands on the outside surface of the cell. In this type of signaling, the ligand does not need to cross the plasma membrane. So, many different kinds of molecules (including large, hydrophilic or "water-loving" ones) may act as ligands. WebO-GlcNAcylation, a posttranslational modification of serine and threonine groups on nuclear and cytoplasmic proteins with O-GlcNAc, is thought to modulate the function and activity of proteins in cells. 6 Reversible O-GlcNAcylation is catalyzed by the nucleocytoplasmic enzymes, OGT and OGA, which adds or removes O-GlcNAc moieties, respectively. 7 O … green bay packer news current
