Melanin Production Pathway

Melanin is synthesised in cytoplasmic organelles called melanosomes, which reside in skin cells and hair follicles called melanocytes. This process is known as melanogenesis.

Bacterial cells often possess molecules of closed, circular DNA, otherwise known as ‘plasmids’. They can also be present at much lower frequencies in certain eukaryotic cell types, such as yeast. They are non-essential, self-replicating DNA molecules which are important for the prokaryotic mobile gene pool.

Role of Transcription Factors

Transcription refers to the creation of a complimentary strand of RNA copied from a DNA sequence. This results in the formation of messenger RNA (mRNA), which is used to synthesize a protein via another process called translation.

Facilitated Transport

Cells continuously move materials in and out through their cell walls. Facilitated transport is one way of moving those materials without expending cellular energy.

Senescence and Aging

Senescence occurs in three different scenarios: senescence due to normal aging; senescence due to age-related diseases, and senescence induced due to therapy

Dielectric Spectroscopy

Dielectric spectroscopy is a type of impedance spectroscopy that measures the dielectric properties of a system as a function of frequency. The external field interacts with the dipole moment of the sample which is expressed as its permittivity.

Cloning Unicellular Organisms

Molecular cloning is usually carried out on one gene or small DNA segment at a time. However, cloning technology has advanced to the stage that scientists have begun cloning genomes of entire unicellular organisms. This approach could be valuable for engineering organisms that thus far have not been amenable to propagation and engineering through conventional laboratory method

Biofilms in Human Disease

A biofilm is a community of microbes on a surface that is encased in a polymer coating. Bacteria that grow attached to surfaces rather than floating in a liquid are called sessile. Most bacteria in nature are sessile, and aggregates of sessile bacteria can form biofilms.

Notch Signaling and Diseases

The notch signaling pathway plays a major role in regulating various cellular processes during development, therefore dysregulation of this pathway can lead to disease.

Horizontal Gene Transfer

Horizontal Gene Transfer (or HGT) is the process of an organism acquiring another organism’s DNA, usually through absorbing the ‘target’ organism, resulting in an endosymbiotic relationship.

Live-cell Lattice Light-sheet Microscopy (LLSM) Applications

Live-cell lattice light-sheet microscopy (LLSM) is a technique for imaging cells rapidly. It has applications in nanoscience and cell membrane visualization.

What Are Cyclins?

The cell cycle is regulated by cyclins, a type of protein that binds and activates cyclin dependent kinases (CDKs).

Krebs Cycle Enzymes

The Krebs cycle, also known as the citric acid cycle, is a series of enzymatic reactions that releases energy from stored carbohydrates, fats, and proteins.
