In yeast, unlike in multicellular organisms, the cell cycle lacks chromosome condensation and is unaffected by cell contacts and cell differentiation. In frog and marine invertebrate oocytes and ...

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 ...

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 ...

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.

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 ...

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 ...

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 ...
