In this article we will discuss about the signalling mechanisms, both in eukaryotes and prokaryotes. 1. Eukaryotic Cell-to-Cell Signaling: The integrative nature of biological systems could be understood after the pioneering work of Claude Bernard (1813-1878) of France. He gave the concept of the miliew interieur and suggested the system of ductless gland (i.e. endocrine glands) for integrating function and [...]
In this article we will discuss about the Mechanism of Protein Synthesis in Prokaryotes and Eukaryotes. Protein synthesis in the cell is conducted by ribosomes that are found attached to the membrane of endoplasmic reticulum and microsomes, as well as in free state in the groundplasm. The main components that take part in protein synthesis at cellular level are: 20 [...]
