fermentation the breakdown of food without the use of oxygen
cell cycle the life cycle of a cell
chromosomes in a eukaryotic cell, one of the structures in the nucleus that are made up of DNA
homologous chromosomes chromosomes that have the same sequence of genes and the same structure
mitosis in eukaryotic cell, a process of cell division that forms two new nuclei
