Replication of Eukaryotic Chromosome | Macromolecules

In this article we will discuss about the replication of eukaryotic chromosome. Taylor in 1958 used radioactive thymidine (3H-thymidine) to label Viciafaba root tip chromosomes. He showed that the chromosomes replicated in a semiconservative manner, and proposed that each chromatid was made up of a single DNA molecule. Thus each sister chromatid is composed of one of the two progeny [...]

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 [...]
