Vasodilation increases blood supply to the damaged area which will help to remove toxic products and dead cells. Increased permeability of blood vessels permits white blood cells and serum proteins to enter into the injured area. These changes occur due to release of chemical alarm signa..

Prokaryotic and Eukaryotic Cells - The structure of the cell that we have studied so far is that of a Eukaryotic cell. How is a Prokaryotic cell different from a Eukaryotic cell? The main difference between these two cell types is that Prokaryotic cells do not have a nuclear membrane..

Chemotherapy is the use of chemicals or drugs to selectively destroy infectious micro-organisms without destroying the live tissues or the host. Paul Ehrlich called drugs as magic bullets and the first milestone of his research was the discovery of Salvarsan for curing syphilis, in 1909. In 1935, G..

You have learnt in the earlier chapters that flow of electrons constitutes an electric current and current can be generated from a battery or a generator. Scientists later discovered that there are many other ways of producing the stream of electrons. This knowledge has led to further dev..

A study of the comparative biochemistry shows that certain similar molecules occur in different groups of animals. This can be compared to the homologous structures. For example, structure of haemoglobin present in man, chimpanzee, gorilla and gibbon show remarkable similarities. Haemoglo..

Bacterial Chromosome - In bacteria, which being prokaryotic organisms, the entire hereditary material is packed into a single, irregularly folded compact mass called nucleoid or genophore or bacterial chromosome. It is short and simple consisting of a single DNA molecule. The DNA is in the form of ..

The coacervates were in a state of dynamic equilibrium, constantly taking in new materials from the oceans and releasing degraded materials. Thus, they had all the basic properties of life such as metabolism, growth and reproduction. However, they lacked the complexity of molecular organization, ca..

. The membrane encloses a clear fluid matrix called nucleoplasm or karyolymph. It encloses a fine network of thread-like structures, called chromatin network. It is composed of chromatin that contain DNA and histones arranged in a specific manner. The chromatin condenses to form distinct ..
