prophase
Prophase
Chromatids condense into an X shape before mitosis. Chromatids are identical strands of chromosomes. After duplication there are 12 chromatids that are in 3 pair of homologous chromosomes.
Phase 1- Mitosis begins. Chromosomes condense from long strands into rodlike structures. Phase 2- The nuclear membrane is dissolved. Paired chromatids align at the cell's equator. Phase 3- The paired chromatids separate and move to opposite sides of the cell. Phase 4- A nuclear membrane forms around each set of chromosomes, and the chromosomes decondense. Mitosis is complete.
The chromosomes will condense during prophase.
The chromosomes coil up and condense during prophase

Prophase
Chromatids are visible during the Prophase of the Cell Cycle, as the chromosomes which chromatids are formed from condense, thus making them visible.
10 chromatids in the G2 phase
DNA replication occurrs through a process called mitosis. The stages of mitosis are (I)PMAT.InterphaseIn the G1 phase, protein synthesis occurrs and mRNA runs along the chromosomes. In the S phase, DNA polymerase runs along the chromosomes/chromatids and creates complementary strands of DNA. In the G2 phase, the 23 chromosomes all have sister chromatids.2. Prophase- Chromosomes condense, spindle fibers form, and the nuclear membrane disintegrates. (23 chromosomes/46 chromatids)3. Metaphase- the chromosomes line up in the middle of the cell and spindle fibers from the centrioles connect to the chromosomes at the kinetochores. (23 chromosomes/46 chromatids)4. Anaphase- Sister chromatids are pulled apart by the spindle fibers to each pole of the cell. (23 chromosomes/46 chromatids)5. Telophase- nuclear envolopes form around the chromatids at each pole, the spindle fibers reduce, the chromatids decondense. (46 chromosomes/ 46 chromatids)Then cytokinesis occurrs to split up the cell into two cells.
The S-phase is during interphase, which means there are no chromosomes. DNA is replicated in the S-phase ("s" for synthesis). It can only be replicated in the form of chromatin, not wrapped up in chromosomes.
Anaphase
chromosomes appear as packets of four chromatids during anaphase. This is when the chromatids start to move and separate in preparation of the creation of four cells.
The phase of mitosis where the chromatin fibers duplicate and condense into visible chromosomes is Interphase. Interphase is the first stage of the cell cycle.
In anaphase, the chromatids separate to form individual chromosomes.
