In the following sections, we’ll walk through the structure of a prokaryotic cell, starting on the outside and moving towards the inside of the cell. WebRepetitive regions at the very ends of chromosomes are called telomeres, and they're found in a wide range of eukaryotic species, from human beings to unicellular protists. Telomeres act as caps that protect the internal regions of the chromosomes, and they're worn down a small amount in each round of DNA replication.

For example, if a cell was undergoing meiosis, and had a total of 4 chromosomes in it, then 2 of them would go to one daughter cell, and 2 of them would go to the other daughter cell. That makes 2 haploid cells.
