The first experiments that correctly identified the molecule that carries genetic information were performed by Oswald Avery.
<u>Option: A</u>
<u>Explanation:</u>
One of the top molecular biologists and well experienced in immunochemistry popular as Oswald Avery, who worked with his colleagues Colin MacLeod and Maclyn McCarty and resulted into most famous study authored by them in 1944, it involves separation of DNA as the material from which genes and chromosomes are produced. He proved DNA was the essence of transformation. DNA was able to convert another strain when isolated from one strain of bacteria, and impart features on that second strain and these DNA contain hereditary knowledge.

Answer:
Genetic modification decreases the genetic variation of the modified organism.
Explanation:
Genetic modification is widely used in agriculture for increasing productivity and to make crops resistant to diseases but along with advantages there are some disadvantages of genetic modification that involve decreases the genetic variation of the modified organism.
<em>This is so because the DNA or genetic material of the modified organisms will have very less diversity as they have grown with the same process and the DNA among the organisms will become similar to each other.</em>
Hence, the correct answer is "Genetic modification decreases the genetic variation of the modified organism."
