What are the differences between mitochondrial dna and chloroplast dna?
Posted February 7, 2023
Basis of differentiation |
Mitochondrial DNA |
Chloroplast DNA |
Definition |
Mitochondrial DNA is present in mitochondria |
Chloroplast DNA is present in chloroplasts of plant cells |
Size |
Human mitochondrial DNA contains approximately 16569 base pairs |
Chloroplast DNA contains approximately 120,000 to 170,000 base pairs |
Number of genes |
37 |
123 |
Location |
Present in the mitochondria of all eukaryotic cells |
Present in the chloroplasts of all plant cells |
Shape of DNA |
It is both circular and linear |
It is primarily circular shaped (only linear shaped in rare cases) |
Abbreviation |
mtDNA |
cpDNA or plastome |
Function |
The genes in the mitochondrial DNA play a role in oxidative phosphorylation for production of ATPs and in synthesis of proteins |
The chloroplast genes play an important role in photosynthesis of plants |
