Published: 18 September 2024
...Charmaine Yan Yu Wong; Hok Ning Tsui; Yue Wang; Karen Wing Yee Yuen ABSTRACT Chromosome segregation errors caused by centromere malfunction can lead to chromosome instability and aneuploidy. In Caenorhabditis elegans , the Argonaute protein CSR-1 is essential for proper chromosome segregation...
