It is thought that both chloroplasts and mitochondria are descended from free-living cyanobacteria, which could explain why they possess DNA that is distinct from the rest of the cell. Chloroplast DNA contains many of the genes necessary for proper chloroplast functioning. A better understanding of the genes in chloroplast deoxyribonucleic acid (cpDNA) has improved the understanding of photosynthesis, and analysis of the deoxyribonucleic acid (DNA) sequence of these genes has been useful in studying the evolutionary history of plants. chloroplast dna.

It occurs mostly in the green algae and higher plants. The chloroplast contains the pigment chlorophyll a and chlorophyll b and DNA and RNA. They also play important role in plant life activity.

The 154 kb chloroplast DNA map of a model flowering plant (Arabidopsis thaliana : Brassicaceae) showing genes and inverted repeats. Chloroplast DNAs are circular, and are typically 120,000–170,000 base pairs long. They can have a contour length of around 30–60 micrometers, and have a mass of about 80–130 million daltons.

Chloroplast DNA (cpDNA) variation has proven to Chloroplasts are organelles with a specific DNA (cpDNA), which are responsible by the energetic metabolism in eukaryotic cells from plants and algae. Their key Chloroplasts have their own DNA, often abbreviated as cpDNA.

They can have a contour length of around 30–60 micrometers, and have a mass of about 80–130 million daltons. The modern chloroplast genome, however, is much reduced in size: over the course of evolution, increasing numbers of chloroplast genes have been transferred to the genome in the cell nucleus. As a result, proteins encoded by nuclear DNA have become essential to chloroplast function. Hence, the outer membrane of the chloroplast, which is freely Chloroplast DNA (cpDNA) is the DNA present in the organelle chloroplast.
