![]() Bacteria can exchange these plasmids with other bacteria, sometimes receiving beneficial new genes that the recipient can add to their chromosomal DNA. Some prokaryotes also have smaller loops of non- essential DNA called plasmids. The region in the cell containing this genetic material is called a nucleoid. In prokaryotes, the genome is composed of a single circular double-stranded DNA molecule. A cell’s DNA, packaged as double-stranded DNA molecules, is called its genome. 13.1.1 Genomic DNAīefore discussing the steps a cell must undertake to replicate, we need a deeper understanding of the structure and function of a cell’s genetic information. The mechanisms involved in the cell cycle are highly regulated. The cell cycle is an orderly sequence of events that describes the stages of a cell’s life from the division of a single parent cell to the production of two genetically identical new daughter cells. The continuity of life from one cell to another has its foundation in the reproduction of cells by way of the cell cycle. Describe the mechanisms of chromosome compaction.Distinguish between chromosomes, genes, and traits.Describe the structure of prokaryotic and eukaryotic genomes.By the end of this section, you will be able to:
