G1 phase. Metabolic changes prepare the cell for division. At a certain point - the restriction point - the cell is committed to division and moves into the S phase.</span><span>
S phase. DNA synthesis replicates the genetic material. Each chromosome now consists of two sister chromatids.</span><span>
G2 phase. Metabolic changes assemble the cytoplasmic materials necessary for mitosis and cytokinesis.</span><span>
M phase. A nuclear division (mitosis) followed by a cell division (cytokinesis).</span></span>
The period between mitotic divisions - that is, G1, S and G2 - is known as interphase.
The answer is 1, either ( AA, Aa, or aa ) .
<span>Adenintriphosphate, also known as ATP, is the main energy carrier of the cell. This occurs because it is a molecule responsible for providing the energy for DNA synthesis; in fact, most metabolic reactions that require energy are associated with ATP and that energy is produced there.</span>
Answer:over time as our evidence improves. The more experiments we do, and the more data we collect, the better our scientific ideas become.
