In this article we will discuss about the translation of amino acid to tRNA in cytoplasm. (i) Activation of Amino acids: Amino acids must be necessarily activated before their involvement in peptide synthesis (Fig. 4-10). The process is accomplished by the binding of an amino acid to ATP enzymatically and its consequent transference to tRNA. (ii) Transfer of amino acid [...]
Quick Notes on Mitochondria:- 1. Introduction to Mitochondria in Cell 2. Origin of Mitochondria in Cell 3. Structure 4. Function. Introduction to Mitochondria in Cell: Mitochondria are membrane bound cell organelles, associated with cellular respiration, the source of energy, being termed as power houses of cell. Mitochondria, discovered by Benda (1898), are present in eukaryotic cells. These are bean-shaped organelles, [...]
In this article we will discuss about:- 1. Types of Plastids in Cell 2. Structure of Chloroplastid 3. Origin 4. Function. Types of Plastids in Cell: Plastids may be coloured or colourless and are of three types. The leucoplasts are the colourless plastids principally serving the purpose of storage. On the basis of nature of storage compound, leucoplastids are amyloplasts [...]
