Mitochondria contain a circular genome molecule, tightly packed with genes.
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.
Molecular geneticist Douglas Wallace talks about the origin of our mitochondria and the DNA within.
Mario Capecchi talks about the possibility of introducing an artificial chromosome into cells to slow the aging process.
Molecular geneticist Douglas Wallace talks about the way mitochondrial DNA is inherited.
