Nipah Virus: An Emerging Threat to Global Health: Nipah virus (NiV) is a zoonotic pathogen that has caused outbreaks in several Asian countries primarily in Bangladesh, Malaysia, India, and Singapore. Nipah virus belongs to the genus Henipavirus. The virus was named after the Malaysian village where it was first identified […]
The molecular basis of inheritance refers to the process by which genetic information is stored, replicated, and transmitted from one generation to the next through the structure and function of DNA and RNA molecules. This MCQ on Molecular Basis of Inheritance will help you to understand the concept clearly. Molecular […]
The lac operon and trp operon are genetic regulatory systems in prokaryotes. The lac operon controls the expression of genes responsible for lactose metabolism, allowing bacteria to use lactose as a carbon source. The trp operon regulates genes involved in tryptophan synthesis, ensuring its production when tryptophan is scarce. This […]
Homology modelling, also known as comparative modelling, is a computational technique in structural biology. It predicts the 3D structure of a protein based on the known structure of a related protein (homolog). It relies on the assumption that structurally similar proteins share similar functions. This is an MCQ on Homology […]
Genetic markers are specific DNA sequences or variations that serve as identifiable points on a person’s or organism’s genome. They are used in genetic research, diagnostics, and ancestry tracing to identify genetic traits, mutations, or associations with diseases, providing valuable insights into an individual’s or population’s genetics. This is an […]
