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 […]

MCQ on Genetic Markers
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 […]

Regulation of Gene Expression in Eukaryotes MCQ
In eukaryotes, regulation of gene expression is a complex process that controls when and to what extent genes are transcribed and translated into proteins. This regulation involves various mechanisms, including transcription factors, chromatin remodelling, RNA processing, and post-translational modifications, ensuring precise control of cellular functions and responses to environmental cues. […]

Types of DNA Repair Mechanisms MCQ
DNA repair mechanisms in cells include base excision repair (BER), nucleotide excision repair (NER), mismatch repair (MMR), homologous recombination (HR), and non-homologous end joining (NHEJ). These pathways correct various types of DNA damage, ensuring genomic stability and preventing mutations that can lead to diseases like cancer. This article on “DNA […]
