What is CRISPR/Cas9? CRISPR/Cas9 stands for Clustered Regularly Interspaced Short Palindromic Repeats/CRISPR-associated protein 9. It is a natural defense mechanism used by bacteria to protect themselves against viral infections. CRISPR/Cas9 is a revolutionary gene editing technology that has transformed the field of genetics and biomedical research. It enables researchers to manipulate and edit DNA sequences […]
Cell viability is the measure of the proportion of living cells in a population. Used to determine the number of living or dead cells in a total sample so the experiment can be optimized if required. It does not differentiate between dividing and non-dividing cells. Viable cells = x Dead cells = y Total cells […]
Every cell in our body produced by a pre-existing cell. process of cell formation from pre-existing cells is known as the cell cycle. Involves in many repetitions of cellular growth and reproduction, nuclear division. Almost all the living cells undergo a cell cycle (some exceptions like RBC). The cell cycle is separated into two phases: […]
Glycolysis is a process of conversion of glucose into pyruvate by a series of intermediate metabolites. Glycolysis is a part of cellular respiration Each chemical modification is performed by a different enzyme. In this process, ATP is formed in the cytoplasm. ATP = energy. Steps of the process Step 1: Phosphate is transferred from ATP […]
Every living organism except viruses has a Cellular organization. Organisms having only a single cell are known as unicellular organisms example bacteria, protozoa. Organisms having multiple cells in their body are known as multicellular organisms. Cells are of two types: Prokaryotic cells Eukaryotic cells The term prokaryote and eukaryote suggested in the 1960s by […]
Cellular respiration is a complex metabolic pathway in which the glucose is broke down and get converted into an energy molecule (ATP).
Cell biology A cell is the smallest unit of life. Cell biology is a field of biological science in which we study the structural and functional properties of a cell. History of cell biology: In 322-384 B.C. Aristotle and Paracelsus concluded that “all animals and plants, however, complicated, are constituted of a few-element which are […]
