Eukaryotes What eukaryotes have plasmids?

Eukaryotes refer to organisms with nuclear membranes and heterokaryon, and are the general names of all single-celled or multicellular organisms with nuclear cells, including protozoa, fungi, plants and animals. All animals, plants, fungi and other organisms with complex subcellular structures wrapped by membranes belong to eukaryotes.

Plasmids generally exist in prokaryotes, but some eukaryotes also exist. Such as yeast, whose plasmid exists in cytoplasm.

1. At present, it is generally believed that plasmids only refer to simple DNA molecules other than chromosomes in bacteria, yeast and actinomycetes.

2. Some plasmids can exist independently in cells or be integrated into chromosomes. This plasmid is called a free body.

3. Most plasmids replicate and transfer independently of chromosomes, and determine some characteristics of bacteria, and their inheritance is similar to cytoplasmic inheritance.
