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 ...

Scientists at EMBL have captured how human chromosomes fold into their signature rod shape during cell division, using a ...

As the cell proceeds through the stages of cell division (from left to right: interphase, prometaphase, metaphase, and anaphase), chromosomes become progressively more compact through a ...

Defects in this process can lead to cell death or diseases like cancer. A new study has shown how chromosomes change shape during cell division. Certain protein complexes help fold DNA into ...

Females have one active X chromosome and one dormant X chromosome in each cell. But a study suggests that genes on the ...

How Chromosomes Shape Up for Cell Division Mar. 24, 2025 — For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead ...

In vertebrate retinas, specialized photoreceptors responsible for color vision (cone cells) arrange themselves in patterns ...

Women have a higher proportion of key immune cells between puberty and menopause, which may be linked to the sex hormone oestrogen and explain why ...
