Do you know?
The discovery of DNA's structure revealed how genetic information is stored and passed on. Tap to read how DNA was discovered.
Watson and Crick
In 1953, James Watson and Francis Crick uncovered the double-helix structure of DNA, changing the course of biology and genetics forever.
Role of Rosalind Franklin's X-ray Images
Rosalind Franklin’s X-ray diffraction images were pivotal in revealing the helical structure of DNA, contributing significantly to Watson and Crick’s model.
The Double-Helix Model
Watson and Crick’s model showed that DNA consists of two strands coiled into a double helix, with base pairs linking the two strands in a specific manner.
DNA’s Role in Genetics
This structure explained how genetic information is stored and replicated, shedding light on how traits are inherited and how organisms grow and develop.
Impact on Molecular Biology
The discovery of the DNA structure launched molecular biology as a field, influencing genetic engineering, biotechnology and medical research.
Modern Implications of DNA
The discovery paved the way for the Human Genome Project, gene therapy, and other advancements, which are transforming medicine, agriculture, and forensics.
