Mitochondria at the crossroads of health and disease

Mitochondria lost most of the bacterial ancestral genome, and many of these genes were transferred to the nucleus: current eukaryotic genomes carry over 600 genes of alpha-proteobacterial origin. 1 The vast majority (99%) of the mitochondrial proteome in humans—over 1,100 proteins—is encoded by the nuclear genome. The …

Cell Cycle

The longest part of the cell cycle is called "interphase" – the phase of growth and DNA replication between mitotic cell divisions. Both mitosis and interphase are divided into smaller sub-phases which …

8 Cell Lysis Methods to Break Cell Walls

This method involves giving the cells a good old grinding. Note that the cells do not have to be suspended in anything for this method to work. This cell lysis method is often used for plant samples frozen in liquid nitrogen since the specimens are comparatively bulky. Also, when you've lysed the cells, metabolites and samples may be ...

The Origin and Evolution of Cells

Cells are divided into two main classes, initially defined by whether they contain a nucleus. Prokaryotic cells (bacteria) lack a nuclear envelope; eukaryotic cells have a nucleus in which the genetic material is separated from the cytoplasm. Prokaryotic cells are generally smaller and simpler than eukaryotic cells; in addition to the absence of a nucleus, their …

Cells and the Versatile Functions of Their Parts

For example, mature red blood cells in mammals lack a nucleus. This gives as much cellular space as possible for a protein called hemoglobin, which allows the cell to carry oxygen from the lungs to the rest of the body. White blood cells are part of the body's immune system and use lysosomes to engulf and destroy bacteria, preventing infection.

Use of a Planetary Ball Mill for Cryogenic Grinding of Yeast Cells

The Michael Rout Lab at the Rockefeller University in New York, NY, initially contacted Retsch Inc. (Newtown, PA) in 2006 to discuss the possibility of using the Planetary Ball Mill to cryogenically grind yeast cell pellets. The aim of the experiment was to explore the construct of nuclear pore complexes located on the cell walls of yeast cells.
