New research into mitotic chromosomes has found that they are covered in a liquid-like coating that could allow them to ...

According to a recent study, mitotic chromosomes are coated in a liquid-like coating that could enable them to bounce off one ...

Chromosomes are a highly condensed form of DNA and are crucial for cell division. During mitosis, chromosomes ensure that the genetic material is equally divided among the daughter cells.

Their results provide a novel insight into mitotic chromosome condensation in living human cells. Their work is published in the journal Proceedings of the National Academy of Sciences ( PNAS ) on ...

By contrast, hyperacetylated mitotic chromosomes lack a defined surface boundary, are frequently perforated by microtubules and are prone to missegregation,” summarized the researchers.

While mitosis is taking place, there is no cell growth and all of the cellular energy is focused on cell division. During prophase, the replicated pairs of chromosomes condense and compact themselves.

To prepare the 46 chromosomes of a human cell for transport to the daughter cells during cell division, each chromosome forms a compact X-shaped structure with two rod-like copies. How the cell ...

Mitosis: Chromosome DNA packed in stacked layers Date: January 8, 2019 Source: Universitat Autonoma de Barcelona Summary: A new study based on electron microscopy techniques at low temperatures ...

A human cell carries in its nucleus two meters of spiraling DNA, split up among the 46 slender, double-helical molecules that are its chromosomes. Most of the time, that DNA looks like a tangled ...

Mitotic chromosomes are pivotal for the inheritance of genetic material. Now, it is already known that chromosomes vary in dimensions among organisms. But what governs mitotic chromosomal size and ...
