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 ...

Each human body cell contains 46 chromosomes. These can be arranged into 23 pairs. Each chromosome in a pair carries the same types of genes. The 23rd pair are the sex chromosomes: In females ...

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 ...

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 ...

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.

B chromosomes manipulate cell division for survival, and new research identifies key genes, including DCR28, involved in this ...

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

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 ...

In healthy DNA replication, at first, each new chromosome gets half of CENP-A ... prevents the loading of CENP-A during most ...
