Proteins: Composition and Structure | Macromolecules

In this article we will discuss about the composition and structure of proteins. Composition of Proteins: Proteins are large molecules consisting of many amino-acids connected by "peptide linkages". Peptide bond is produced when carboxyl radical of one amino acid reacts with the amino (-NH2) group of the other amino acid. The basic structural formula of amino acids is shown in [...]

Genetic Code: Degeneracy and Universality | Protein

In this article we will discuss about:- 1. Subject-Matter of Genetic Code 2. Degeneracy of Genetic Code 3. Universality of the Genetic Code. Subject-Matter of Genetic Code: The information stored in DNA is in the form of code. DNA contains 4 bases, A, T, G and C, whereas, proteins are made of 20 different amino acids. Therefore, the genetic code [...]

Steps Involved in Mechanism of Protein Synthesis

The following points highlight the three main steps involved in mechanism of protein synthesis. The steps are: 1. Initiation of Protein Synthesis 2. Elongation of Polypeptide 3. Termination of Protein Synthesis. Mechanism of Protein Synthesis: Step # 1. Initiation of Protein Synthesis: (i) Amino Acid Activation: The amino acid (AA) is activated by the enzyme "aminoacylsynthetase", and energy is provided [...]
