Mitochondrial matrix
The cytosolic, intermembrane space, compartment has a water content of 3.8 μl/mg protein, while the mitochondrial matrix 0.8 μl/mg protein. It is not known how mitochondria maintain osmotic balance across the inner mitochondrial membrane, although the membrane contains aquaporins that are believed to be conduits for regulated water transport. Mitochondrial matrix has a pH of about 7.8. Mitochondrial DNA was discovered by Nash and Margit in 1963. One to many double stranded mainly circular DNA is present in mitochondrial matrix. Mitochondrial DNA is 1% of total DNA of a cell. It is rich in Guanine and Cytosine content. Mitochondria of mammals have 55s ribosomes.
Friedrich Miescher Institute for Biomedical Research
The Friedrich Miescher Award is Switzerland's highest honor for up-and-coming biochemical researchers. The award is granted every year by the Swiss Society for Biochemistry to the best scientific contribution in this field. Prize winners must be under 40 and must either be Swiss citizens or have conducted the prize-winning research in this country. The award was instituted in 1970, proposed and donated by the FMI. It is named after the Basel scientist who discovered DNA, Friedrich Miescher.
