WebThe replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis. The elucidation of the structure of the double helix provided a hint as to how DNA is copied. Recall that adenine nucleotides pair with thymine nucleotides, and cytosine with guanine. WebApr 14, 2024 · A. Respiration. B. Diffusion. C. Osmosis. D. Transpiration. Answer:- B. Diffusion Oxygen moves throughout the cell membrane through a procedure called diffusion. Diffusion can be explained as the molecule’s movement from a superior concentration region to a section of lower concentration.
