Thin Layer Chromatography

Thin layer chromatography is used to analyse mixtures: determine the number, identity, and purity of compounds present in a mixture. This technique can also be used to visualize the progress of a reaction.

What is Mitohormesis?

Mitohormesis is a process wherein reactive oxygen species (ROS) produced by mitochondria at a low concentration act as signaling molecules to initiate a cascade of cellular events that ultimately protect the cells from harmful effects.

Chromatin Remodeling: Mechanisms and Importance

Chromatin remodeling is an important mechanism of regulating eukaryotic gene expression, which makes tightly condensed DNA accessible to various regulatory factors, such as transcription factors and components of DNA replication.

The Lac Operon in E. Coli

Required for the transport and metabolism of lactose in Escherichia Coli (E. coli).The lactose operon or lac operon consists of three structural genes namely lacZ, lacY, and lacA that encode proteins involved in lactose metabolism as well as several regulatory genes.

What are P-Bodies?

P-bodies are dynamic ribonucleoprotein granules found in the cell cytoplasm. They are primarily composed of translationally repressed mRNAs and proteins associated with mRNA decay machinery.

What is Aspergillus niger?

The fungus Aspergillus niger is a type of mould, which can sometimes be attributed to the cause of some cases of pneumonia. It is also the causative agent of ‘black mould’ on the outsides of certain foods, such as apricots, onions, grapes, etc - therefore making Aspergillus niger a food ‘spoilage’ organism.

What is Expansion Microscopy?

Expansion microscopy, put simply, is a method of improving the final image resolution during regular light microscopy, by physically enlarging the organism itself.

16S rRNA Sequencing

For centuries the classification of living organisms into distinct groups and species was done by morphology. While this was sufficient for Darwin and early biologists to study evolution and relatedness of some organisms, this method becomes difficult when characteristics vary.

Lung Organoids: Methodology, Research and Applications

The lungs are comprised of a complex branching system, lined with highly specialized cells. These cells facilitate several crucial functions, such as oxygen exchange, but also immune functions to protect this vulnerable part of the body from infection.

What is the Carbohydrate-Active Enzyme Classification System?

The Carbohydrate-Active enZYme (CAZymes) classification system is a database that contains the knowledge of enzymes that are involved in the formation and break down of complex carbohydrates and glycoconjugates. The database classifies each enzyme based on its role.
