The process in which a gene from one organism is inserted into the DNA of another organism is called genetic engineering or recombinant DNA technology. It is done to transfer the desirable trait of one organism to another to produce a better organism.
Calcium is a chemical element with symbol Ca and atomic number 20. Calcium is a soft gray Group 2 alkaline earth metal, fifth-most-abundant element by mass in the Earth's crust. The ion Ca2+ is also the fifth-most-abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and sulfate.[5] Free calcium metal is too reactive to occur in nature. Calcium is produced in supernova nucleosynthesis.
The number of mitochondria per cell varies widely; for example, in humans, erythrocytes (red blood cells) do not contain any mitochondria, whereas liver cells and muscle cells may contain hundreds or even thousands. The only eukaryotic organism known to lack mitochondria is the oxymonad Monocercomonoides species.
This model suggests that the cell membrane is a dynamic structure, because the proteins and phospholipids move laterally within the lipid bilayer ( so it is more of a fluid than solid)
