In 1958, just five years after Watson and Crick discovery of the double helix, a lingering question gripped the molecular biology community: How, exactly, does DNA duplicate itself? Matthew Meselson and Franklin Stahl solved this riddle with an experiment so elegant…
Have you ever wondered how your body knows how to build itself—cell by cell, organ by organ? The answer lies in DNA (Deoxyribonucleic Acid). DNA is the genetic instruction manual of life. From the color of your eyes to how…
You’ve probably heard of DNA—the famous molecule that holds the instructions for life. But what is DNA actually made of? The answer is nucleotides. Think of nucleotides as tiny, powerful building blocks. They come together like Legos to form the long…
Translation in prokaryotes is a highly coordinated, energy-driven process involving mRNA, tRNA, ribosome, and many accessory factors. The Central Dogma of Molecular Biology explains the flow of genetic information as: DNA → RNA → Protein Once a gene is transcribed…
The Central Dogma of Molecular Biology is the fundamental principle that explains how genetic information flows inside cells. Biology is full of beautiful simplicity hidden within complex processes. One of the most fundamental frameworks in molecular biology is the central…
Prokaryotes have special arrangement of genes on chromosome. This arrangement known as operon. However, operons are not found in eukaryotes. Operon is present only in prokaryotes. There is more than one gene in an operon. Genes present in an operon…
Operons are set of genes which are present on chromosome of all prokaryotes. Lac operon is one such operon which helps E. coli to to metabolize lactose. In E. coli glucose is the primary carbon source for energy production. E…
