In the telophase of mitosis each satellited chromosome gives riso to a nucleolus, while in a chromosome with a secondary constriction the nucleolus arises at the constriction.

Mitosis occurs in five stages: prophase, prometaphase, metaphase, anaphase and telophase. Metaphase chromosomes oscillate while attached to growing and shrinking microtubules. Here, the authors ...

All organisms need to ensure that no DNA segments are rereplicated in a single cell cycle. Eukaryotes achieve this through a process called origin licensing, which involves tight spatiotemporal ...
