Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Who’s discovery made it obvious that heritable factors and the genes on chromosomes are composed of DNA?
A
James Watson
B
Francis Crick
C
Rosalind Franklin
D
Maurice Wilkins
Explanation: 

Detailed explanation-1: -James Watson, in full James Dewey Watson, (born April 6, 1928, Chicago, Illinois, U.S.), American geneticist and biophysicist who played a crucial role in the discovery of the molecular structure of deoxyribonucleic acid (DNA), the substance that is the basis of heredity.

Detailed explanation-2: -Figure 4: Oswald Avery’s work helped establish DNA as hereditary material. Data from Avery’s experiments.

Detailed explanation-3: -The chromosome theory of inheritance was developed primarily by Walter Sutton and Theodor Boveri. They first presented the idea that the genetic material passed down from parent to child is within the chromosomes. Their work helped explain the inheritance? patterns that Gregor Mendel had observed over a century before.

Detailed explanation-4: -Francis Crick (1916-2004) was one of Britain’s great scientists. He is best known for his work with James Watson which led to the identification of the structure of DNA in 1953, drawing on the work of Maurice Wilkins, Rosalind Franklin and others.
