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 […]
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. […]
A cell cycle checkpoint is a regulatory control point in the cell cycle where various signalling pathways assess the fidelity of DNA replication and repair, ensuring that cell division proceeds accurately, preventing the propagation of genetic errors or damaged DNA. This article on Checkpoints of Cell Cycle MCQ will help […]
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 […]
DNA barcoding is a molecular technique that uses a short, standardized DNA sequence from a specific gene to identify and classify species. It helps scientists and researchers accurately distinguish and catalogue organisms, aiding in biodiversity research, conservation, and various scientific applications. This post is on applications of DNA barcoding MCQ […]
