study membrane proteins scientists

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. The nuclear material consist..

In conventional X-rays an overlap of organs occurs and often difficult to interpret. These diagnostic difficulties have been eliminated by the use of an X-ray technique called computer Tomography (CT) scaning or computerised Axial Tomography (CAT) Scanning. CT Scan is a radiologic technique, which ..

The mathematical models which tells to optimise (minimize or maximise) the objective function Z subject to certain condition on the variables is called a Linear programming problem (LPP). During World War II, the military managements in the U.K and the USA engaged a team of scient..

Introduction - 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..

The knowledge of viscosity and its variation with temperature, helps us select a suitable lubricant for a given machine. Viscosity of organic liquids such as proteins and cellulose, helps us calculate their molecular weight and determine their shape. The knowledge of viscosity hel..

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 a double helix which fo..

In 1961, two French microbiologists, Francois Jacob and Jacques Monod proposed a mechanism, called Operon Hypothesis , for the regulation of gene action in E. coli. It got them the Nobel Prize in 1965. fig. 23.1 - Francois Jacob and Jacques Monod with their Colleague They found that the addit..

. 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 ..

The muscular tissue is a tissue that is capable of bringing about different types of movements in the body. It is one of the highly specialized animal tissues. It is a derivative of mesoderm. The muscular tissue exhibits a unique property called contractibility. It is the capacity of the cells to e..
