The CRISPR-Cas system is an immune mechanism used by bacteria and archaea to defend against viruses. In recent years, it has become a transformative tool in the field of gene editing revolution.CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) are sequences found in the genomes of microorganisms. These sequences contain genetic material derived from viruses (bacteriophages) previously encountered by the bacteria. CRISPR sequences work with Cas (CRISPR-associated) proteins to rec

Night blindness, or nyctalopia in medical terminology, refers to a condition in which an individual experiences reduced vision in dark or dimly lit environments. This condition is typically not a standalone disease but rather a symptom of an underlying disorder of the visual system.Pathophysiology and CausesThe main cause of night blindness is the dysfunction of rod cells in the retina. The retina is composed of rods and cones, which detect light and transmit visual signals to the brain. Rod cel

Genetic engineering is a field of biotechnology that aims to directly modify the genetic structure of organisms by altering adding or removing elements from their DNA. This technology is applied in many areas including increasing agricultural production developing medical treatments and improving industry processes like.HistoryThe foundations of genetic engineering were laid in the 19th century with the work of Gregor Mendel on pea plants. The discovery of the DNA double spiral structure by Jame
