The cellular biology is a wide and versatile area of research. Your mind cannot imagine the huge number of chemical reactions that take place inside the cell. Each cell is comprised of organelles which each has a special function related to its unique structure. Each...
Overview of cell biology
By: Tarek Musslimani
In this article I will discuss the biology of the cellular membrane and the biology of the organelle inside the cell, which is called the mitochondria. In addition, I will discuss the important process of protein trnaslation which occurs on the cellular ribosomes. The cell...
