The process of Adsorption is usually studied through graphs know as adsorption isotherm. It is the graph between the amounts of adsorbate ..
Bromine is a chemical element of the Halogen family with atomic number 35. It is represented by symbol Br. It is a diatomic molecule and exists as reddish brown liquid state. Bromine ion (Br-) occurs in sea water in soluble compounds form. An interesting fact about Bromine is that it is only non-metallic element which exists in liquid form.
Chlorine is an important chemical element of the Halogen family. Chlorine is represented by chemical symbol Cl and has atomic number 17. It exists as a diatomic, yellow green gas. Most abundant compound of Chlorine is Sodium Chloride (NaCl).It is a weaker oxidizing agent in comparison to Fluorine (F2)....
Iodine is a chemical element of the Halogen family with atomic number 53. It is represented by symbol I. It exists as diatomic solid, I2(S).Iodine is an essential part of our diet deficiency of which cause Goiter. Chile saltpeter contains trace amount of Sodium Iodate (NaIO3) and Sodium Periodate (NaIO4) as impurity. An important property of Chile saltpeter is that it is soluble in water while its impurities....
Fluorine is the first chemical element of the Halogen family. It is represented by symbol F and has atomic number 9. Fluorine is an extremely reactive element and reacts with itself to form Fluorine Gas (F2 (g)) which has light yellow color. It is the 13th most abundant element by weight. During 1813, Humphry Davy performed set of experiments and proved the presence of new element, which he called Fluorine. Though his experiments established the presence of Fluorine....
A restriction enzyme (or restriction endonucleases) recognizes a specific base pair sequence in DNA called a restriction site and cleaves the DNA (hydrolyses the phosphodiester backbones) within the sequence. Restriction enzymes are widely found in prokaryotes and provide protection to the host cell by destroying foreign DNA that makes entry to it .It acts as a part of defense mechanism.
Genetic engineering also called as recombinant DNA technology, facilitates the manipulation and duplication of DNA pieces, for industrial, medical and research purposes. “Engineering” word in genetic engineering is assigned for designing, construction and manipulation according to a set plan. The benefits of genetic engineering have been realized in wide array of fields.
A cloning vector is a DNA molecule in which foreign DNA can be inserted or integrated and which is further capable of replicating within host cell to produce multiple clones of recombinant DNA. Such a vector is called Cloning Vector. Plasmids and phages are the vectors used for cloning purposes, particularly in prokaryotes (bacteria).
Humulin is synthetic human insulin prepared by using genetic engineering. Humulin is manufactured from DNA sources in laboratory, using recombinant DNA technology. Synthetic insulin is also called genetically engineered insulin. The synthetic insulin (humulin) is as effective as hormone insulin secreted by human pancreas.
The production of technologies based on genetic engineering is often referred as modern biotechnology. With the improvement of genetic engineering ....
According to Einstein ‘Time is what a clock reads’. Any phenomenon that repeats itself regularly can serve as a measure of time. Human heart which beats regularly, rotation of earth around its axis, revolution of earth around the sun are some examples of repetitive phenomena’s, which serve as measures of time.
Concept of Mass is defined as quantity of matter contained in a body. The mass of a body is actually the quantity of matter in it, which can never be zero. There are two different kinds of masses of a body. The values of the two types of masses of a body are same. Inertial mass of a body is the measure of inertia and gravitational mass of a body is a measure of gravitational pull....
