Molecular biology is a scientific field concerned with exploring cell structure, their chemical composition and functions at a molecular level.

💡 DNA Extraction 🧬 It is the process of isolating DNA from cells or tissues to study its structure, sequence, or function. This process involves breaking open cells, separating DNA from other cellular components, and purifying it for analysis. DNA extraction is more than just a lab technique; it's a process rooted in biochemistry and molecular biology principles. Steps of DNA Extraction: • Step 1: Cell Lysis (Breaking the Cells) Cells are surrounded by membranes made of…

In 2015, three scientists won the Nobel Prize in Chemistry for decades of research into DNA—research that reinforces the idea that evolution is mythology and makes the modern evolutionary theory of abiogenesis seem more and more indefensible.

Bands of DNA in an electrophoretic gel form only if most of the DNA molecules are of the same size, such as following a PCR reaction, or restriction digestion of a plasmid. In other situations, such as after restriction digestion of chromosomal (genomic) DNA, there will be a large number of variable size fragments in the digest and it will appear as a continuous smear of DNA, rather than distinct bands.

CRISPR. Starting with its definition, we explain how this technology harnesses an ancient bacteria-based defense system — and how it will impact the world around us today

DNA (deoxyribonucleic acid) is a set of instructions for creating the proteins that make your body work. Two strands of DNA together form into a double helix.
