Google is paying tribute to a scientist who played a key role in helping us understanding how DNA works.
Google's logo on Tuesday honors Har Gobind Khorana, who won The Nobel Prize in 1968 for his gene research. According to a biography on the Nobel website, his exact date of his birth is not known, but documents show he was born on this day in 1922.
Along with fellow researchers Robert Holley and Marshall Nirenberg, Khorana discovered how molecules called nucleotides in DNA determine which amino acids are built. The acids from proteins that carry out basic cell functions.
All three were awarded the Nobel in 1968 for their research.
Less than five years later, Khorana created the first synthetic gene. Khorana's efforts earned him several awards, including the National Medal of Science in 1987 for "his innovative contributions that significantly contributed to our understanding of gene structure, membrane function and vision."
Khorana died in November 2011.
