Yet another critical cell cycle checkpoint takes place mid-mitosis. This check determines whether the chromosomes in the cell have properly attached to the spindle, or the network of microtubules ...

Prometaphase is an extremely dynamic part of the cell cycle. Microtubules rapidly assemble and disassemble as they grow out of the centrosomes, seeking out attachment sites at chromosome ...

When looking at cells with a microscope, the length of different stages of the cell cycle can be estimated using the formula: \(\text{Length of time in phase}=\) \(\frac{\text{observed number of ...

With only half the DNA, when the parent cell combines with another parent ... Others cells in your body contain 46 chromosomes: 23 from your father and 23 from your mother. Your egg (or sperm ...

During meiosis, the cell division process central to sexual reproduction, all chromosomes must figure out where to destroy ...

Relationship of shape, structural dynamics, and function with the cellular state and gene expression Cell cycle, chromosome structure, nuclear matrix, cytoskeleton, organelles, nucleocytoplasmic ...

Cytokinesis is a key event in the cell cycle requiring tight coordination of mitotic spindle assembly, actomyosin contractility and membrane dynamics, but the mechanisms that regulate cytokinesis are ...

Initiation must be triggered at the appropriate time in the cell cycle at many hundreds or thousands of separate sites (origins of DNA replication) in the parental chromosomes. However, initiation ...

The shape and location of chromosomes during the post-division interphase of the cell cycle impacts gene function because it brings non-adjacent regions into contact, such as enhancer sequences ...

it must grow and make copies of all the organelles such as mitochondria and ribosomes. The cell must also replicate the chromosomes in the nucleus, then it can divide by mitosis.
