In normal cells, phosphatidylserine (PS) residues are found in the inner membrane of the cytoplasmic membrane. During apoptosis, the PS residues are translocated in the membrane and are externalised. In general, though not always, this is an intermediate event in apoptosis and is tho ...
细胞凋亡中染色体 DNA 的断裂是个渐进的分阶段的过程，染色体 DNA 首先在内源性的核酸水解酶的作用下降解为50-300kb的大片段。然后大约30 ﹪的染色体 DNA 在Ca ² 和Mg ² 依赖的核酸内切酶作用下，在核小体单位之间被随机切断，形成180～200bp核小体 DNA 多聚体。 D ...
Many individuals are not aware of the distinction between glutamic acid, glutamine and glutamate. Glutamic acid is an organic acid that is considered a "brain nutrient." It has been used with varying degrees of success in learn ...
