Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For ...

引言你可能还记得在生物课本上见过的，细胞分裂时那清晰的X形染色体，它们是生命密码的载体，在细胞分裂过程中扮演着至关重要的角色。然而，你是否曾好奇，这些看似简单的“小棍子”是如何从长长的DNA分子，一步步折叠、浓缩成如此高度有序的结构？长期以来，研究人 ...

论文通讯作者、EMBL高级科学家Jan Ellenberg说，“我们的最新论文标志着我们理解细胞如何将染色体打包以准确分配到子细胞中的一个里程碑。这将是了解重新调整基因组以实现忠实遗传的分子机制的基础，从而合理预测如何在未来预防这一过程中出现导致人类疾病的错误。”（ 生物谷 Bioon.com） ...
