Yeasts are unicellular prokaryotic organisms. They cannot be seen by naked eyes and hence we need to observe them microscopically. Introduction: Yeasts are unicellular and microscopic fungi. They are commercially used in bread and wine making industries. They multiply asexually by following budding method. The shape and size varies from species to species of yeast […]

Paper Chromatography is an analytical technique used for separation, detection and identification of biomolecules. Chromatography is a fundamental technique for the separation, detection, identification of chemical species from a mixture. As it is called as analytical technique because it is used for qualitative and quantitative studies of separated components from mixture. The chromatography consists of two

Introduction- Human Hairs are strands of protein which come out from skin. It help us regulate our body temperature and afford protection. Human hairs have various colors like black, brown, blond, and grey and have distinguished patterns like straight, curly and wavy. The characteristics of hair depend on our genes, however, environmental conditions also exert

INTRODUCTION CRISPR is a specific, efficient and versatile gene-editing technology we can harness to modify, delete or correct precise regions of our DNA. Dr. Emmanuelle Charpentier & Dr. Jennifer Doudna co-invented CRISPR/Cas9 gene editing. In the year 2020 both the scientists who pioneered the revolutionary gene-editing technology got Nobel Prize in Chemistry. Until then, people

Endospore is the resistant form of bacteria which is very difficult to kill. Sporulation: Sporulation is a spore forming process in bacteria. Spores are metabolically inactive and resistant form of bacteria. The spore becomes resistant to chemical, heat, dehydration and radiation. The spores do not multiply. The bacteria with the ability of undergoing sporulation are

Flagella is the motility organelle of the bacteria. Introduction: Flagella is known as motility or locomotor organelle and it looks hair like appendage. They are longer than pilli and fimbriae. Their structure is rigid and slender. The bacteria are able to swim in liquid media is due to the rotating movement of flagella. To perceive

Introduction: DNA Replication is a vital molecular process of duplicating the genetic material. During cell division, the newly formed DNA is transferred into the daughter cell. DNA is passed from one generation to another because it consists of genes that carry the information of protein synthesis. To carry out DNA replication, the cell needs replication

Introduction: Cloning term is a quite known term to biologist. For a newbie, the cloning term might be limited to make copy of an organism and creating clones. But when we talk about Gene cloning in Molecular Biology and Genetic Engineering, it means making copies of segment of DNA or desired gene. The gene cloning

DNA polymerase synthesize complementary daughter strand by reading the DNA template. Introduction: Bacterial DNA replication is a vital event in which the cell makes a copy of its genetic material with the help of DNA polymerase. The newly replicated DNA is transferred to the next generation via cell division. The principle of DNA replication is

Bacterial DNA replication is an essential step for reproduction – Binary fission. Introduction: DNA replication is a process in which organisms duplicate their DNA molecule or make its exact copy in order to transfer the genetic information into its daughter cell (next generation). Hence, DNA replication occurs before cell division. DNA replication ensures that both
