During cell division, chromosomes are duplicated and separated so that one copy of each chromosome is inherited by each of the two emerging daughter cells. Correct distribution of chromosomes requires ...

Cells can measure how long they spend in mitosis. If mitosis is prolonged due to problems during chromosome separation, the Mitotic Stopwatch Complex is formed, which may lead to cell arrest or cell ...

Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the ...

A team from the Bellvitge Biomedical Research Institute (IDIBELL) and the University of Barcelona (UB), in collaboration with a researcher from the Mayo Clinic and the University of Minnesota, have ...

One of the worst things that can happen to a cell is to end up with the wrong number of chromosomes. This can happen if something goes wrong during cell division, and it can lead to infertility, ...

For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...

A mixture of DNA and proteins—known as "chromatin"—sits inside every cell nucleus as a jumbled puddle of genetic information. As cells prepare to divide during mitosis, the chromatin is condensed into ...

This important study demonstrates that a peri-nuclear actomyosin network, present in some types of human cells, facilitates kinetochore-spindle attachment of chromosomes in unfavorable locations - ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

The clear rubber chip sitting under a microscope in Stephen Quake’s lab is a complex maze of tiny channels, chambers, and pumps, hooked up to thin plastic tubes that supply reagents and control ...
