What had the previous discoveries of Sutton, Morgan and other scientists narrowed the search to?

Options

  1. AThe mechanism for genetic inheritance
  2. BThe molecule responsible for genetic inheritance
  3. CThe chromosomes located in the nucleus of most cells
  4. DThe transformation principle

Correct answer

C. The chromosomes located in the nucleus of most cells

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
