DNA Basics

Articles explaining the fundamental concepts of DNA and its structure. Topics include its discovery, molecular properties, biological importance, protein synthesis, and sequencing methods.

All About DNA and Proteins

DNA contains genes that instruct your cells how to make proteins, which perform nearly every function your body needs to survive.

An Overview of DNA Functions

DNA carries your genetic instructions for proteins, cell growth and reproduction, forming the biological blueprint that keeps your body working.

DNA Sequencing

DNA sequencing determines the order of bases in your DNA to reveal genetic information that shapes who you are.

How Was DNA Discovered?

The scientists and experiments that led to Watson and Crick uncovering DNA's double helix structure in the 1950s.

Learn About DNA Structure

DNA is a twisted ladder made of stacked bases called nucleotides, a structure Watson and Crick revealed in the 1950s using Franklin's crucial X-ray image.

The Importance of DNA

Understanding DNA has transformed disease diagnosis, treatment, and how we identify genetic risks that shape modern medicine.

The Properties of DNA

DNA has a double helix structure held together by hydrogen bonds, with base pairing rules that enable it to copy itself.

What Is DNA?

DNA is the genetic material in your cells that carries inherited information, made up of four bases and stored in chromosomes.
