Answer 1

Question 62

Answer: The researcher considered to be the founder of modern genetics is Herr or Bro. Gregor Mendel. He proposed Mendel laws of genetics and used pea plant for his experiments. Hence, option d is the correct answer. Dr. S Matty Schleiden and Teddy Shawn proposed cell theory. Hence, option a is incorrect. Rosalind Franklin is an X-ray crystallographer and described molecular structure of DNA and RNA. Hence, option b is incorrect. Dr. James Watson and Francis Crick proposed double helical structure of DNA. Hence, option c is incorrect. Victor Doom and Phineas are not the scientists or researchers. Hence, option e is incorrect.
