Abstract. A plant cell contains three genomes: in the nucleus, the mitochondria, and the plastids. The size of the genomes is given in base pairs (bp). ... The DNA of the genome is replicated during the interphase of mitosis and generates in this way a quadruple chromosome set.

Are genomes in every cell?

When we talk about our genome — all the DNA in our cells — we speak in the singular. But over the course of decades, it has become clear that the genome doesn't just vary from person to person. It also varies from cell to cell. The condition is not uncommon: We are all mosaics.

What cells have a genome?

Germ cells only have one copy of the genome made up of 3 billion base pairs of DNA. When sperm and egg cells combine, that results in two genomes. Some cells like skin, hair, and nail cells don't have any genomes. They start off with genomes in order to grow properly.
