These answers are, well, misguided. The number of chromosomes visible at the beginning of mitosis is whatever the full complement of chromosomes is for that organism. In humans, it would be 46. As mitosis proceeds, these are replicated to 92, but at the very beginning of mitosis you would still have the diploid number.
The beginning of mitosis is marked by the condensation of chromatin into visible chromosomes. This process is known as prophase.
At the beginning of mitosis, each chromosome is duplicated and consists of two identical sister chromatids joined together. Therefore, the number of visible chromosomes at the start of mitosis is equal to the number of unique chromosomes in the cell. This number varies depending on the organism, but for humans, there are 46 visible chromosomes at the beginning of mitosis.
At the beginning of mitosis, the amount of DNA is the same as at the end. The DNA is replicated during the S phase of interphase to form sister chromatids, which separate during mitosis and result in two daughter cells with the same amount of DNA as the parent cell.
Cytokinesis typically occurs during the telophase stage of mitosis, just after the separation of the duplicated genetic material into two distinct nuclei. It involves the physical division of the cytoplasm, leading to the formation of two separate daughter cells.
Two chromatids are present in a chromosome at the beginning of mitosis.

Mitosis occurs during the last phase- Telophase.

The equatorial plate happens in mitosis during cytokineses.

telophase is the point at which the two nuclei are divided and cell membrane is pinched to form a daughter cell
There are five stages of mitosis, beginning with interphase and ending with telophase. Interphase is the longest phase, during which the centrioles and DNA replicate and preparations are made for mitosis to occur.
