Solution
The correct option is D Nucleus
The test tube containing the radioactive nucleotides was used for the culturing of the plant cells. The DNA is composed of the nucleotides and uses the radiolabelled nucleotides for the synthesis of DNA during replication. The DNA in the plant cells is present in the nucleus. So, when these cells are examined, the radioactive nucleotides are found inside the nucleus.Thus, the correct answer is option D.
