Web概述. 減數分裂始於雙倍體細胞，這些細胞具有兩個相同的染色體，稱為同源染色體。 首先，細胞進行dna複製，每條同源染色體分別由兩個姊妹染色單體組成，然後每組同源染色體會互相進行同源重組，同源染色體之間形成物理性結合。 减数分裂i时，同源染色體藉由紡錘體引導分離，形成第一組 ... WebChromosomes are involved in a series of directed movements during both mitosis and meiosis. With the separation of the sister chromatids/homologues at anaphase, the equilibrium is broken, the chromosomes move towards the poles at the rate of about 1 pm/min. By hydro-dynamic analysis it has been calculated that a force of about 10-11 …
