Introduction: Cystic fibrosis (CF) is a hereditary condition that impacts the respiratory, digestive, and reproductive systems. It is caused by a mutation in the gene that codes for a protein called cystic fibrosis transmembrane conductance regulator (CFTR). This protein regulates the movement of salt and water in and out of cells, and is involved in […]

Myobacteria were the first bacterial infections to be discovered in humans, and they continue to cause serious illnesses till date. Robert Koch described the bacterium that causes tuberculosis in 1882. Since then, a vast number of mycobacterial species that cause pulmonary and extrapulmonary infections in humans and wildlife have been reported. Two primary pathogenic organisms,

Introduction: Chromosomes are thread-like structures that are found in the nucleus of both animal and plant cells. Each cell’s nucleus contains chromosomes that bundle the DNA molecule. DNA, a type of nucleic acid, is tightly wrapped around proteins called histones that stabilize the organization of each chromosome. History: In the late 1800s, scientists using a
