Mitochondria and chloroplasts are organelles in eukaryotic cells involved in respiration and These maps describe how combinations of DNA variants (genotypes) system in which genetically different nuclei coexist in the same cytoplasm.

e. Large chunks of chloroplast DNA have been found in plant nuclear genomes, and the rice genome even has an intact mitochondrial genome integrated into one of its chromosomes. There seems to be a constant flood of organellar DNA bombarding the nucleus and integrating into the nuclear genome (Martin, 2003; Kleine et al., 2009). The nucleus is a cell’s central organelle, which contains the cell’s DNA (Figure 3.6). The cytoplasm is composed of two parts, the cytosol and organelles.

A mitochondrion or chloroplast has multiple copies of its DNA, and a typical cell has many mitochondria (and, in the case of a plant cell, chloroplasts). In plant cells, DNA is present inside the nucleus, inside the mitochondria, and also inside the chloroplasts. In prokaryotic cells, like those of the bacterial cells, a single circular chromosome is present in the cytoplasm as they don’t have a nucleus, and a double-stranded DNA is present inside the Plasmids.
About 10 percent of a chloroplast's proteins are encoded by its own DNA. The rest come The rest comes from the DNA in the nucleus of the cell. Protoplastids have two membranes, just like the outer and inner membrane of a chlo

the chloroplast to the nucleus. The remaining chloroplast encoded genes are not identical across the plant kingdom indicating an ongoing transfer of genes from the organelle to the nucleus. Scope: This review focuses on the active processes by which the nuclear genome might be acquiring or removing DNA sequences from the chloroplast genome. Present
The DNA in the nucleus of a eukaryote is coiled up in the form of chromosomes. Most chloroplast proteins are encoded by the nucleus, chloroplast ribosomes consist of 52 proteins but only 19 of them are encoded by plastid genome. cpDNA is transmitted maternally in most flowering plants, biparentally in a few, and paternally in gymnosperms. cpDNA genes have been shown to transpose to the nucleus and there is good evidence that mtDNA, cpDNA, and nuclear genomes exchange genes. The presence of chloroplast-related DNA sequences in the nuclear genome is generally regarded as a relic of the process by which genes have been transferred from the chloroplast to the nucleus. The remaining chloroplast encoded genes are not identical across the plant kingdom indicating an ongoing transfer of genes from the organelle to the nucleus.

What are the Similarities Between Mitochondrial DNA and Chloroplast DNA? Mitochondrial DNA and chloroplast DNA are single, circular chromosomes.

The nucleus communicates with the rest of the cell through the nuclear pores. The nucleus is like a vault. It holds the cell's DNA -- which contains the genetic instructions for the cell's activities. In the diagram there is a structure within the nucleus called the nucleolus.
