dna fingerprinting important

DNA Finger Prints - The technique of finger printing was perfected by British genetist Dr. Alec Jeffreys in 1984. fig. 25.9 Identical Twins No two people (other than identical twins) have exactly the same sequence of bases in their DNA. By detecting these, the differences in ..

A gel is immersed in a buffered solution, and then DNA fragments from individuals are added to the gel. When an electric current is applied to the solution, one end of the gel takes on a negative charge, and the other end a positive charge. DNA molecules carry a negative charge ..

Mechanism of DNA Replication - It is a complex process and involves the participation of over a dozen enzymes and other protein factors. The intertwined DNA starts separating from a particular point and this is known as the origin of replication. The second step is that the two ..

The consistency of DNA copying during reproduction is important, which leads to the stability of population species. Changes in ecological system, which are beyond our control like varying temperature, varying water levels and natural calamities, can wipe out the population spe..

, (+) - thyroxine, has none of this effect but is used to lower the cholesterol levels. In foods, the chirality of compounds determines the nutritional value, sensory properties or biological activity. Enantiomers of a chemical may have very different flavors. Detection of an unnatural ratio of ena..

Biotechnology is the use of technological procedures in the field of biology for obtaining products of commercial importance. Biotechnology is the use of technological procedures in the field of biology for obtaining products of commercial importance. Biotechnology has two main as..

Phosphate esters play a vital role in the life processes. The most important of these biomolecules are DNA, RNA, adenosine mono-, di- and tri- phosphates (AMP, ADP and ATP). Hydrolysis of P-O-P link in ADP releases energy, which can be put to useful wor..

It also forms the bone along with calcium as calcium phosphate. It is present in the nucleic acids - RNA and DNA as phosphoric acid. It is necessary for the formation of ATP which are the energy molecules of the cells. Thus, phosphate has an important metabolic role. Phosphorus..

Mitosis - This type of cell division occurs in the somatic (body) cells. Here a diploid (2n) parent cell gives rise to two diploid (2n) daughter cells. For the purpose of description mitosis is divided into four stages - Prophase Metaphase Anaphase Telophase It is important to understand ..
