Feeder Pathway – Pathways, Mechanism, Importance

Feeder Pathways for Glycolysis

Feeder pathway is the metabolic process in which different non-glucose carbohydrates are changed into intermediates that can enter glycolysis. It is the process that allows fructose, galactose, mannose and stored polysaccharides like glycogen to be converted into common glycolytic compounds. These intermediates then move into the normal glycolytic steps for further breakdown. In this pathway … Read more

Models of Energy Flow in a Ecosystem – Linear and Y-shaped food chains

Models of Energy Flow in a Ecosystem - Linear and Y-shaped food chains

Energy flow in an ecosystem is the process by which energy is transferred from one trophic level to the next, and it is always unidirectional. It is the sun that acts as the major source of energy for most ecosystems and this solar energy is captured by the producers through photosynthesis. It is converted into … Read more

Transposable elements – Definition, Types, Examples, Application

Transposable elements - Definition, Types, Examples, Application

Transposable elements can be described as mobile genetic segments that is able to move from one position of the genome to another without the need of any homology. It is the process where small DNA sequences is shifted or sometimes replicated inside the chromosomes, and this movement is referred to as transposition. It is seen … Read more

Transposition – Definition, Types, Mechanism

Transposition - Definition, Types, Mechanism

What is Transposition? Transposition is the process in which a particular DNA sequence is shifted from one position of the genome to another position. It is the movement of a transposable element or jumping gene, and it is not dependent on any homologous sequence at the target site. It is the process that may occur … Read more

Different Types of Immunological Techniques With Examples

Different Types of Immunological Techniques With Examples

Immunological techniques is the set of laboratory methods that is based on the specific antigen–antibody reaction, and it is used to detect, identify or measure different biological substances in a sample. It is the process where an antibody binds with its corresponding antigen and this binding is used for locating proteins, hormones, pathogens or other … Read more

Types of Immunoelectrophoresis Techniques- Principle, Uses

Types of Immunoelectrophoresis 

Immunoelectrophoresis (IEP) is the process in which proteins of a biological sample are first separated by electrophoresis and then allowed to react with specific antibodies inside a gel. It is the technique combining electrophoresis with immunodiffusion. In this method the sample like serum is placed on an agarose gel and an electric field is applied, … Read more

Production Media – Types, Characteristics, Examples, Uses

Production Media - Definition, Characteristics, Examples, Uses

What is Production Media? Production media is the nutrient-rich medium used to support the large-scale growth of microorganisms or cell cultures for the purpose of producing useful biological substances. It is designed in such a way that optimum growth conditions is maintained, and the metabolic activities of the organisms is supported for yielding products like … Read more

Galactose (Gal) Operon – Structure, Regulation

Galactose (Gal) Operon - Structure, Regulation

What is Gal operon? The galactose operon is the unit in bacteria that is responsible for the metabolism of D-galactose, and it is organized with four structural genes (galE, galT, galK and galM). It is the process where these genes are required both for catabolic breakdown of galactose and for anabolic formation of compounds like … Read more
