Mendelian Genetics - The biggest name in the entire history of genetics beyond any doubt is that of Gregor Johann Mendel (1822-1884). It was Mendel, more than any other scientist, who synthesized the basic principles of heredity into a body of knowledge that has formed the very core of mo..

As the theory of chemical evolution started gaining more support, investigations were initiated by several scientists to establish the conditions under which, the simplest organic compounds were formed in the primitive earth. Two scientists, Stanley Miller and Harold Urey ..

Leeuwenhoek (1632-1723), the Dutch lens maker was the first person to observe human sperm. He held that each sperm was a potential human being and could develop into an offspring when introduced into the womb of a woman. Scientists like Swammerdam and Malpighi strongly advocated the idea ..

Chronology of Significant Events in Cell Biology - CHRONOLOGY OF SIGNIFICANT EVENTS IN CELL BIOLOGY YEAR EVENT 1500 Jansen designed the first conpound microscope by containing two lenses. 1665 Robert Hooke examined a thin section of bottle cork and described the basic unit as 'c..

In the recent years, many modern techniques have been developed which have enabled scientists to manipulate the genetic material. These include recombinant DNA technology, transformation and transductio..

Chromosomes (chroma = colour, soma = body) are tiny thread-like structures found in the nucleus of a cell. In a non-dividing cell they appear as a chromatin network while during cell division they become condensed to form short and thick chromosomes. Chromosomes are unique cell structures which are..
