are pulled toward opposite ends of the cell.

chromosomes line up along the equator of the cell

chromosomes begin to decondense and the two new nuclei begin to form.

Detailed explanation-1: -At the beginning of mitosis, the chromosomes condense, the nucleolus disappears, and the nuclear envelope breaks down, resulting in the release of most of the contents of the nucleus into the cytoplasm.
Detailed explanation-2: -During mitosis, the nuclear envelope disintegrates and the chromosomes (shown in red) line up in the metaphase plate. The chromosomes are pulled apart and the cell starts to divide. During the early stages, individual tubules of the endoplasmatic reticulum (ER; shown in green) bind directly to chromatin.
Detailed explanation-3: -During metaphase, the nuclear membrane disappears and the chromosomes become aligned half way between the centrioles.
Detailed explanation-4: -Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.
