While prokaryotic cells do not have membrane-bound structures, they do have distinct cellular regions (Figure 1). In prokaryotic cells, DNA bundles together in a region called the nucleoid. Primitive ...

Velia Fowler (standing), chair of the Department of Biological Sciences and pioneering researcher in the architecture of cells, examines F-actin and other proteins in the structure of red blood cells ...

This basic structure of a plant cell is shown below - the same plant cell, as viewed with the light microscope, and with a transmission electron microscope. Figure caption, A generalised plant cell ...

This basic structure of a plant cell is shown below – the same plant cell, as viewed with the light microscope, and with the transmission electron microscope. Animal and plant cells have certain ...

To study living organisms at ever smaller length scales, scientists must devise new techniques to overcome the so-called diffraction limit. This is the intrinsic limitation on a microscope's ability ...

Scientists have discovered a mysterious new structure lurking inside every human cell. These tiny structures, dubbed hemifusomes, are just 200 to 400 nanometres in diameter. To put that into ...

In a recent study published in the journal Nature, a large team of researchers from the United States (U.S.) used single-cell ribonucleic acid (RNA) sequencing combined with high-resolution ...

A hidden structure inside the cell is rewriting how scientists understand leukemia. Beneath the microscope, what looked like disorder turned out to follow a simple physical rule – one that connects ...
