Mitochondria contain a circular genome molecule, tightly packed with genes.
Mitochondria are the power stations of eukaryotic cells.
DNA found in the mitochondrion of a cell differs in structure and is separate from the DNA found in the cell nucleus. Mitochondrial DNA, or mtDNA, exists as a circular loop of double-stranded DNA rather than the linear form found in nuclear DNA. However,
Matt Ridley talks about Mitochondrial DNA.
DNAFTB Animation 30: Ivan Wallin presents his idea that mitochondria and chloroplasts were once free-living organisms.
Unlike nuclear DNA, mtDNA is Â inherited solely from the mother. (Mitochondria are predominantly from the motherâs egg and not from the fatherâs sperm.) Therefore, mtDNA sequences or orders of nucleotides generally remain constant over many generation
Human mitochondrial DNA is 16,569 base pairs in length.
