text: DNA is Circular in Shape
text: Mitochondrial DNA is a circular molecule.
text: Although the mitochondrial DNA is very small compared to nuclear chromosomes, it codes for 13 proteins involved in mitochondrial energy production and specific tRNAs.
text: Mitochondria have their own circular DNA, RNA molecules, ribosomes (the 70s), and few other molecules that help in protein synthesis.
text: Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts.
text: The mitochondria, and thus mitochondrial DNA, are passed almost exclusively from Mitochondrial DNA is the small circular chromosome found inside mitochondria.
text: Importantly, the DNA in mitochondria and chloroplasts is not the same as the DNA in the nucleus, and the DNA in the mitochondria and chloroplasts is circular in shape, which is also the shape of DNA in prokaryotes (single-celled organisms without a nucleus).
text: That’s why mitochondria are semi-autonomous and have their own DNA, which is circular just as in bacteria.
text: They contain their own DNA, which is circular as is true with bacteria, along with their own transcriptional and translational machinery.
text: This endosymbiont theory would also explain why the mitochondria had its own DNA and why this DNA is circular.
text: Mitochondrial DNA is a circular molecule.
