All modern organisms fall into two classes, eukaryotes and prokaryotes. Eukaryotes (from the Greek meaning “true kernel”) have a cell nucleus that harbours most of the cell’s genetic information and ...

Prokaryotic cells, which include all bacteria and archaea, are ancient, and relatively simple compared to eukaryotic cells, which are found in fungi, plants, and animals. Scientists have long sought ...

Scientists at the Macquarie University in Australia worked with an international team of scientists to achieve a major milestone in synthetic biology by completing the creation of the final chromosome ...

In early cytological studies chromatids of metaphase chromosomes were suggested to coil into a spiral called chromonema. This assumption was recently supported by chromosomce conformation capture ...

Chromosomes are thread-like structures comprising DNA that are present inside the nucleus of every cell in the body. Specific segments of DNA are called genes. Every chromosome contains many genes, ...

The origin of organisms with complex cells, known as eukaryotes, is one of the most crucial parts of life’s evolutionary story. All animals, plants, and fungi are eukaryotes, and if complex cells had ...

Modern eukaryotic cells have proteins that enable chromosome segregation during cell division, new discoveries shed light on their origin in simpler prokaryotic organisms. Modern nucleated (eukaryotic ...
