Molecular Structure of Nucleic Acids | Biochemistry

In this article we will discuss about the molecular structure of nucleic acids, explained with the help of suitable diagrams. Nucleic acids are macromolecules present in all living cells, either in free state, or in combination with proteins to form nucleoproteins. Besides, the simplest viruses consist exclusively of a molecule of nucleic acid enclosed in a protein shell. We will [...]

Molecular Structure of Centromere

In this article we will discuss about the molecular structure of centromere. Eukaryotic chromosomes possess a segregational device called centromere which is responsible for the chromosomc movement during cell division. Chromosome fragments without a centromere (acentric fragments) are unable to move to any of the poles during cell division; as a result, they are excluded from the daughter nuclei and [...]
