Hydrogen Bonding – Types and its Nature

A hydrogen bond is a special type of dipole-dipole attraction which occurs when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons. These bonds are generally stronger than ordinary dipole-dipole and dispersion …

VITAMINS: What are Vitamins and its sources (Basic Guide)

In developed countries, vitamin deficiencies result mainly from poverty, food fads, drugs, or alcoholism. Vitamin toxicity (hypervitaminosis) usually results from taking mega doses of Vitamin A, D, B6, or niacin. Vitamins may be fat soluble (vitamins A, D, E, and K) and water-soluble (B and C …

Glycolysis : Glucose Oxidative Pathway at Cellular levels

Glycolysis literally means “splitting of sugar“. The pathway is also called “EMP Pathway” and “Glucose oxidative pathway“. In glycolysis, Glucose (a six-carbon sugar) is split into two molecules of three-carbon sugar. Glycolysis yields two molecules of ATP (free energy containing molecule), two molecules of pyruvic acid …

microRNA : Special class Post-Transcriptional Regulators

MicroRNA is a class of post-transcriptional regulators. They are short ~22 nucleotide RNA sequences that bind to complementary sequences in the 3’ UTR of multiple target mRNAs, usually resulting in their silencing. MicroRNAs target ~60% of all genes, are abundantly present in all human cells and …

What are the Enzymes involved in DNA Replication

A fundamental property of living organisms is their ability to reproduce. Bacteria and fungi can divide to produce daughter cells that are identical to the parental cells. Sexually reproducing organisms produce offspring that are similar to themselves. This article covers Enzymes involved in DNA Replication.  On a …
