tumor formation in lung cancer

Lung cancer (Part 1)

Lung cancer is a medical condition in which abnormal cells grow and develop in the lungs, the organs used for breathing. These abnormal cells divide, and the increase in the number of cells leads to growths called tumors. The abnormal cells cause harm to the

Genome editing by CRISPR technique

CRISPR/Cas9

CRISPR technique is powerful tool for genome editing. It serves the purpose of genome alteration or modification. Cas9 protein is an enzyme which acts a molecular scissor for cutting and editing the genome sequence. The potential applications of CRISPR technique include correcting and modifying gene

the concept of marker free transgenic plants

Marker free transgenic plants

The term transgenic plants applies for those having modified genome by addition of some foreign gene in them. This purpose is to provide the plants with some qualities that are not naturally present in them are to improve the already present qualities. For example, the

Bioenergetics- the study of cellular metabolism

Bioenergetics

Bioenergetics is the scientific study concerned with the flow of energy among organisms at cellular level and is based upon the principles of biochemistry and molecular biology. Energy production in organisms involves certain processes ranging from photosynthesis in plants and that of oxidation metabolism in

‘Beauty is in the eyes of beholder.’ But the cosmetics brands  will tell you something else, setting their own  ‘standard’ of beauty. This is what our society does as mostly people think that fair skin is the standard of being beautiful. If you have brown

epigenetic modification in plants

Epigenetics in plants

Epigenetics is a phenomena that involves changes in activity of genes and their expression. Their basis is alterations in chromosomal structures and not the changes in DNA sequence of the chromosomes. Thus, epigenetics refers to any phenotypic variations that are heritable. Above all, these are

bioremediation techniques

Bioremediation of oil spills

An oil spill is a form of pollution that involves the release of petroleum into the biosphere especially the waterways such as oceans, posing a huge threat to marine life. These spills may occur as a result of a physical harm to oil tankers that

uses of industrial enzymes

Industrial enzymes

Enzymes are biological catalysts that speed up the biochemical reactions. For living organism, enzymes are of pivotal importance as without them, the biochemical reactions proceed at very slow rate. Likewise, enzymes also used in commercial applications. Industrial enzymes have wide applications in product manufacturing. Industrial

hemolytic anemia-autoimmune disorder

Autoimmune hemolytic anemia (AIHA)

Autoimmune hemolytic anemia is a disorder in which the person’s immune system generates auto-reactive antibodies that destroys the red blood cell of the person leading to lower level of blood cell in body. The life time of normal RBC reduces to just few days instead
