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 [...]
The below mentioned article provides an overview on Cells and Organisms Used in Molecular Biology. For any molecular biological work or genetic engineering, the synthesis and cloning of any recombinant DNA involves introduction of this DNA into bacteria. Structure of E. coli: Among bacteria, escherichia coli are suitable for this purpose for the following reasons: i. It can be grown [...]
In this article we will discuss about Genetic Material:- 1. Properties of Genetic Material 2. Evidence of Genetic Material. Properties of Genetic Material: A living cell is composed of several inorganic and organic components. Among them, one will obviously act as genetic material responsible for controlling hereditary characters. Identification of this genetic material remained controversial for a long time. Now [...]
