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 […]
Category: Cell Biology
cell biology is a field of biology. in this field, we study the structure and functioning of the cell, and cellular components such as mitochondria, ribosome, the structure of the cell, types of cells.
CELL VIABILITY ASSAY
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 […]
CELL CYCLE
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 | Role of NAD and NADP
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 […]
Prokaryotic Vs. Eukaryotic cell
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
Cellular respiration is a complex metabolic pathway in which the glucose is broke down and get converted into an energy molecule (ATP).
History of Cell Biology
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 […]
