Bacteria cells are single-celled microorganisms that lack a distinct nucleus and membrane-bound organelles. They have a simple structure with a cell wall and a plasma membrane that encloses the cytoplasm and genetic material. Bacteria play important roles in various ecological processes and can be beneficial or harmful to other organisms, including humans.

Chromosomes are structures within cells that contain genetic material in the form of DNA. Each chromosome consists of a long DNA molecule wound around proteins called histones. The DNA in a chromosome carries genes, which are the instructions for building and maintaining an organism. Chromosomes come in pairs, with one inherited from each parent, and are organized into different regions such as telomeres, centromeres, and chromatin.
The four phases of mitosis are prophase, metaphase, anaphase, and telophase. These phases are part of the cell division process where the genetic material is distributed equally into two daughter cells.
Chromosomes first appear to be double during the S phase of the cell cycle when DNA replication occurs. This results in two identical sister chromatids joined by a centromere in preparation for cell division.
