Starch casein agar can be described as an nutrient-rich medium that is used for the cultivation and growth of the saccharolytic marine bacteria.
The fact that they are both cells that are eukaryotic, meaning they have a real nucleus that is enclosed and separate from other organelles through a nuclear membrane is a key element which determines their ways of multiplication. They share the same reproduction process of meiosis and mitosis by using their DNA, which is stored in the cell’s nucleus.
What is Biometrics? What is Numerical Taxonomy?
