What is the contribution of Dr Har Gobind Khorana?
Har Gobind Khorana made important contributions to this field by building different RNA chains with the help of enzymes. Using these enzymes, he was able to produce proteins. The amino acid sequences of these proteins then solved the rest of the puzzle.
What was the contribution of Har Gobind Khorana in genetic code?
We believe in the free flow of information He was 6 before he owned his first pencil. Khorana emerged from this background to receive a Nobel Prize in 1968 for deciphering the genetic code that translates DNA sequences into the protein molecules that carry out the functions of living cells.
Who is Hari Gobind Khorana?
Har Gobind Khorana, (born January 9, 1922?, Raipur, India [now Raipur, Pakistan]—died November 9, 2011, Concord, Massachusetts, U.S.), Indian-born American biochemist who shared the 1968 Nobel Prize for Physiology or Medicine with Marshall W. Nirenberg and Robert W.
Who made first artificial gene?
Har Gobind Khorana
Synthesis of the first complete gene, a yeast tRNA, was demonstrated by Har Gobind Khorana and coworkers in 1972.
What did Har Gobind Khorana invent?
Khorana was the first scientist to chemically synthesize oligonucleotides. This achievement, in the 1970s, was also the world’s first synthetic gene; in later years, the process has become widespread. Subsequent scientists referred to his research while advancing genome editing with the CRISPR/Cas9 system.
What is the contribution of Marshall Nirenberg?
In 1961 Marshall Nirenberg, a young biochemist at the National Institute of Arthritic and Metabolic Diseases, discovered the first “triplet”—a sequence of three bases of DNA that codes for one of the twenty amino acids that serve as the building blocks of proteins.
Who is credited with creating the first accurate model of DNA Rosalind Franklin?
At King’s College London, Rosalind Franklin obtained images of DNA using X-ray crystallography, an idea first broached by Maurice Wilkins. Franklin’s images allowed James Watson and Francis Crick to create their famous two-strand, or double-helix, model. In 1962 Watson (b.
