Therefore, in this review, we summarize the localization, recruitment, activation, and functions of Aurora-B in mitosis and oocyte meiosis. The accurate regulation...

However, the application of SC analysis to fish chromosomes is limited by the associated complications. First, in most fish, meiosis does...

...Qiqi Sun; Feng Liu; Xiaolong Mo; Bo Yao; Guanghai Liu; Shanshan Chen; Yanping Ren Correct regulation of cohesin at chromosome arms and centromeres and accurate kinetochore-microtubule connections are significant for proper chromosome segregation. At anaphase of meiosis I, cohesin at chromosome arms...

The chromosome pairing level and the number of ring bivalents were different for each line. Besides rod bivalents...
