1 A country is part of a continent, which itself is part of the whole earth. 2  Asia, Australia, Antarctica, Africa, North America, South America, Europe are the seven land masses that are called continents.3  There are over 190 countries in the world. 4  Countries are separated geographically, politically and culturally.ummary. 1  A country is part of a continent, which itself is part of the whole earth. 2  Asia, Australia, Antarctica, Africa, North America, South America, Europe are the seven land masses that are called continents.
The short answer: No. Mitochondria are the power-house of the cell. It is where the Electron Transport Chain takes place as well as the production site almost all of the ATP a cell produces. Proteins are produced by ribosomes of the rough endoplasmic reticulum.Okay... the answer above is only partially true.itochondria are the power-house of the cell. It is where the Electron Transport Chain takes place as well as the production site almost all of the ATP a cell produces.
Mitochondrial DNA (mtDNA) is normally present at thousands of copies per cell and is packaged into several hundred higher-order structures termed nucleoids.The abundant mtDNA-binding protein TFAM (transcription factor A, mitochondrial) regulates nucleoid architecture, abundance and segregation.e next examined the involvement of the cytosolic DNA sensor cGAS in mtDNA stress signalling, as it mediates ISG expression in response to exogenous and endogenous immunostimulatory DNA species. Knockdown of cGAS in Tfam+/â MEFs or TFAM depletion in cGasâ/â MEFs largely abrogated ISG expression (Fig. 2a).
