Including chromosome assembly and segregation
Chromatin remodeling plays a central role in the regulation of gene expression by providing the transcription machinery with dynamic access to an otherwise tightly packaged genome. Further, nucleosome movement by chromatin remodelers is essential to several important biological processes, including chromosome assembly and segregation, DNA replication and repair, embryoni… WebApr 19, 2024 · Cancer cells display persistent underlying chromosomal instability that results in chromosome mis-segregation, the formation of micronuclei, and abnormal numbers of chromosomes (aneuploidy).
