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 [...]

Centromere: Structure and Types | Chromosomes

In this article we will discuss about Centromere:- 1. Structure of Centromere 2. Types of Centromere. Structure of Centromere: The site of constriction in a chromosome under light microscope is generally taken as the po­sition of centromere. It is generally believed that constitutive heterochromatin is present in the centromeric region. The component of centromere is mainly the kinetochore, and DNA [...]
