Learn about the ultrastructure and organelles of animal, plant, fungal and bacterial cells. BBC Bitesize Scotland revision for SQA National 5 Biology.

Chromosomes are defined as thread-like structures of deoxyribonucleic acid DNA that carry hereditary information for everything from height to eye color. They are found in the nucleus of a cell ...

"Every single cell can have a different chromosome structure," Cheng, a Curators' Distinguished Professor of Electrical Engineering and Computer Science, said.

It has been known for several years that abnormal chromosome numbers lead to protein imbalances in the affected cells. Researchers at RPTU have now investigated the detailed effects of such imbalances ...

Researchers at the IPK Leibniz Institute have discovered a previously unknown protein that is central to plant reproduction. The protein SCEP3 enables plants to mix and precisely distribute their ...

Centromeres are important elements of chromosomes that are responsible for the proper separation of chromosomes during cell division. This function is closely related to appropriate methylation ...

When cells prepare to divide, their DNA is tightly wound around proteins to form chromosomes that provide structure and support for genetic material.

The ideal crop plant is tasty and high-yielding while also being resistant to diseases and pests. But if the relevant genes are far apart on a chromosome, some of these positive traits can be lost ...

This CENP-A centromere identifier attracts other proteins, and in cell division builds a massive structure, the kinetochore, for pulling the duplicated chromosomes apart during cell division.
