Cytokinesis did not occur properly during the cell cycle. Ie. the splitting of the cytoplasm was not done. hence the genetic materials are separated in two distinct nuclear envelope. if this continued of non-cytokinesis,then more distinct nuclei can occur
Cytoplasmic division of a cell at the end of mitosis or meiosis. it happens during the nuclear division phase called anaphase, which continues through telophase.
Answer:
The correct answer will be-
1. Observation-option B.
2. Hypothesis-option A.
3. Experiments- option C.
Explanation:
A scientific method involves various steps to explain a natural phenomenon of nature. It begins with making an observation which leads to asking the scientific question. The researcher does background research and proposes a hypothesis which could be tested through experiments. The experiments could prove or disprove the hypothesis based on the results.
In the given question the observation made is an equal amount of A and T and G and C are observed. It leads to a hypothesis which shows that this could have happened due to the winding of two strands of DNA and the experiments was performed through X-ray diffraction pattern.
Thus, the selected options are the correct answer.
