Which are replicated during interphase? sister chromatids chromosomes centromeres nuclei
2 answers:
I believe the correct answer is chromosomes.
<h2>Explanation:</h2>The cell cycle is divided into 2 phases i.e. the interphase and mitosis phase. The mitosis phase has 4 stages namely the G1, S, G2 and G0 stage. In the synthesis stage, the cell replicates its chromosomes to produce 2 identical sister chromatids.
<h2>Further Explanation:</h2>The cell cycle interphase stage starts with the G1 stage. Sometimes, a G0 stage may exist depending on the cell. Only cells that do not differentiate enter this stage and stay until they die. The only cells that enter this stage are the neurons and the cardiac cells (cells that form the heart tissue). In the G1 stage of the interphase, the cell accumulates proteins and energy needed for the cell cycle. The cellular DNA is also checked for any errors and if any are found, the cycle terminates. The cell then enters the S or the synthesis phase where DNA and protein synthesis occurs. The chromosomes double up to form 2 identical sister chromatids that will be divided once the cell forms an identical daughter cell. It also prepares for thenext stage. G2 is the next stage and the cell again checks for errors and mutations in the DNA and then doubles up its organelles and cellular inclusions in preparation for mitosis. That is where the Interphase stage ends. The next stage is mitosis and is divided into the nucleus division stage (Karyokinesis) and cytoplasm division stage (cytokinesis). Mitosis has 5 stages i.e. Prophase, Prometaphase, Metaphase, Anaphase and Telophase. Cytokinesis overlaps with telophase and in some cells it does not occur and if it fails to occur, then the cell that is formed will e multinucleate. In the end, the cell will pinch at the center and the 2 identical daughter cells start to function as separate entities.
