Correct Answer - Option 1 : Arthur Kornberg

The correct answer is Arthur Kornberg.

  • Arthur Kornberg synthesized the DNA in Vitro.
  • The first DNA polymerase is isolated by Arthur Kornberg, in 1959 and he was the first person who synthesized the first DNA molecule in vitro.
  • Arthur Kornberg had won the Nobel Prize in Medicine 1959 for his discovery of "the mechanisms in the biological synthesis of deoxyribonucleic acid" together with Dr Severo Ochoa of New York University.

  • DNA:
    • DNA, or deoxyribonucleic acid, is the inherited material found in every single living creature.
    • The deoxyribonucleic acid in an individual’s chromosomes controls a variety of visible characteristics and invisible characteristics.
    • Visible characteristics include race, colouring, and sex.
    • An invisible characteristic includes blood groups and susceptibility to inherited diseases.
    • Deoxyribonucleic acid is made up of molecules called nucleotides.
    • Each nucleotide contains a sugar group, a phosphate group, and a nitrogen base.
    • The four types of nitrogen bases are adenine (A), thymine (T), guanine (G), and cytosine (C). Adenine and thymine are paired by two H bonds, whereas cytosine and guanine are paired by three H bonds.
    • Deoxyribonucleic acid is the same in all of the cells in the body of an individual.

  • Discoverers and their discoveries:
    • Robert Hooke - Universal Joint, Balance Wheel, and Diaphragm.
    • Edward Jenner - Smallpox Vaccine.
    • Joseph Lister - Carbolic Acid.
