Plasmids: Definition, Types, Properties, Functions, Applications

Plasmids

J. Lederberg invented the term plasmids. Plasmids are independent self-replicating DNA molecules that exist as separate, extrachromosomal genetic components in bacteria. They are also found in some eukaryotes, such as yeast. Plasmids are replicons. Replicons are self-replicating nucleic acid molecules. Natural plasmids have … Read more

Biosynthesis of purine nucleotides

Purines are heterocyclic aromatic compounds containing two fused rings. They are the most common nitrogen-containing heterocycles in nature. Purine is also present in significant amounts in red meat, beef, pig, dry peas, beans, lentils, and oats. The purine ring is … Read more

Nucleic Acids- Definition, Types, Components, Functions

Nucleic Acid

Friedrich Miescher first isolated nucleic acid from the nuclei of leukocytes from discarded surgical bandages and named it nuclein. Nuclein was later discovered to be a combination of basic protein and phosphorous-containing organic acid, now known as nucleic acid. Nucleic … Read more

Glycolysis- Definition and 10 Steps with Diagram

Glycolysis

Glycolysis is an oxidative process that converts one mole of glucose into two moles of pyruvate through a series of enzymatic reactions. It is also known as the Embden-Meyerhof pathway. The pyruvate obtained from the glycolysis process further enters into … Read more
