Animal Cell culture is a technique of growing animal cells in artificial media and laboratory conditions. In order to grow in the laboratory, the cells are isolated from host and inoculated in appropriate media. The function of media is to provide all the essential nutrients that are required for growth and multiplication. The in-vitro method […]

Stem cells are the backbone for all types of cells and tissue in our body. They are undifferentiated cells which have the ability to form different types of cells of our body. The embryonic stem cell have the ability to to form whole body whereas, other stem cells have their limitations. All the stem cells

Animal Biotechnology is the branch of Biotechnology that deals with genetical modification of animals to improve their quality and productivity. It also deals with the production of therapeutic valuable compounds in animals. The Applications of Animal Biotechnology are in the field of Agriculture, Pharmaceutical and Dairy Industries. The animals are genetically modified at cellular and

We all are aware that whoever is born will die some day. This principle is also applied to fundamental form of life i.e. cells. Death of cells is essential for maintaining the cell population. The death of cells can be natural or could be caused by unfavourable conditions or injury. Apoptosis and Necrosis are two

Stem cells are the progenitor cells that further differentiate into different types of cells. They are called the foundation for forming tissue, organs and body. The stem cells maintain their population and renew themselves by cell division. There are different types of stem cells based on the ability to form a range of differentiated cells.

Summary- Gene is a segment of DNA or RNA that encodes for a functional protein. The main objective of plant biotechnology is to create new varieties of cultivated plants by manipulating DNA molecule. Nowadays, Gene transfer methods has become the most versatile and easy to handle protocols for improving crop production and for study or

All living organisms are connected in a complex web of relationship like symbiotic (mutual relationship), parasitic (utilize host material and cause damage), pathogenic (utilize host material and may kill it) and Commensalism (where one partner gets benefit while other is not affected). The human body provides ideal habitat for pathogenic organisms and hence, we get

History of Vaccines – Immunology is the branch of life Science that deals with the study of immune system of living organisms. Recovering of people from diseases led the foundation of this branch. Our ancestors had observed that people recovered from diseases had become resistant to that particular disease. The attempts of inducing immunity were

Transduction is the process by which foreign DNA is introduced into a bacterial cell by a bacterial virus or a bacteriophage. Bacteriophage is a virus that infects and replicates within a bacterium. Bacteria are host for bacteriophage. It is capable of attaching to the bacterial cell wall and injecting its DNA to the bacterium. Inside

What Globular Protein is? A Globular protein is a Spherical or Globular shaped protein, made by the folding of different segments of a poly-peptide chain. These are the the most abundant proteins in nature. It has a three dimensional structure containing α-helices and β-sheets folded into a compact structure which is stabilized by both polar
