 * 1953 -** **[|James Watson]**, an American geneticist, and **[|Francis Crick]**, a British biophysicist, discovered the structure of DNA. To do this, they used X-ray photographs of DNA taken by New Zealand biophysicist **[|Maurice Wilkins]**. Until this time, it was not known how DNA made a copy of itself in order to transmit genetic information to other cells. The three men won the Nobel Prize for their discovery in 1962.
 * 1960’s -** Marshall Nirenberg, an American biochemist, and Har Gobind Khorana, an American biochemist born in India, decoded DNA and discovered the building blocks of DNA. This code consists of four chemical units, represented by the letters A (adenine), T (thymine), C (cytosine), and G (guanine). Each string of letters produces a specific Amino Acid. When these Amino Acids are combined, they create human traits such as eye color and genetic diseases.
