Discovering DNA
Deoxyribonucleic acid
, or DNA, is considered the building block of life. As the blue print for all genetic information, DNA
is the molecule that directs biological development and heredity. It is responsible for the characteristics and functions of all living things.
From early on, scientists knew that if they could gain a solid understanding of
genetics
and DNA, they would be able to
ultimately improve the quality of life.
The discovery of DNA started in the late nineteenth century when the laws of genetics were defined. Soon after this, the location of DNA
was determined to be in the nucleus of the cell. Scientists identified the basic molecular components of DNA and the relationship between DNA and inherited
traits. They developed an x-ray of DNA, and in 1953, the structure of DNA was finally announced.
Through knowing and understanding the structure and biological roles of DNA, scientists have been able to develop many applications and techniques for
identifying individuals, verifying relationships, pinpointing illnesses, and improving the overall quality of life.
