When was the discovery of nuclein made?

Options

  1. AAt the same time as the proposition of principles of inheritance by Mendel
  2. BBefore the discovery of the principles of inheritance by Mendel
  3. CAfter the discovery of the principles of inheritance by Mendel
  4. DIn the 20th century

Correct answer

A. At the same time as the proposition of principles of inheritance by Mendel

Step-by-step solution

Even though the discovery of nuclei by Meischer and the proposition for principles of inheritance by Mendel were almost at the same time , the fact that DNA acts as a genetic material took a long time to be discovered and proven. By 1926, the quest to determine the mechanism for genetic inheritance had reached the molecular level. Previous discoveries by Gregor Mendel, Walter Sutton, Thomas Hunt Morgan and numerous other scientists had narrowed the search to the chromosomes located in the nucleus of most cells. But
