DNA (Deoxyribonucleic acid) is the fundamental molecule that carries the genetic instructions for the development, functioning, growth, and reproduction of all known organisms. It is famously shaped like a double helix, a structure resembling a twisted ladder.
The twisted ladder structure is composed of two main parts:
The Backbone: The outer rails of the ladder are made of alternating sugar (deoxyribose) and phosphate molecules. This backbone runs in opposite directions on each strand, known as antiparallel orientation.
The Rungs (Base Pairs): Connecting the two rails are pairs of four nitrogenous bases: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). They pair specifically: A always bonds with T, and G always bonds with C.https://jayasundhar.blogspot.com/
It’s a great, clear primer on DNA’s double-helix structure—especially the antiparallel backbone and the specific A–T / G–C base pairing. If you ever want to connect this to listening discoveries, RadioFM Pro could be a fun parallel way to explore patterns across languages and regions.
