DNAFTB Animation 30: Ivan Wallin presents his idea that mitochondria and chloroplasts were once free-living organisms.
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,
Human mitochondrial DNA is 16,569 base pairs in length.
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
A mitochondrion has several copies of its own genome, and there are several hundred mitochondria per cell. (image of mitochondrion)
Organelles in a typical animal cell.
Leland Hartwell describes how cells regulate the timing of growth and cell division. Bob Horvitz and Mike Hengartner explain control mechanisms for cell death.
The human mitochondrial genome consists of a DNA ring of about 16,570 nucleotides. It contains 37 genes, most of which are coding for mitochondrial tRNAs.
Compounds inherent in berries, pomegranate juice, wine and green tea have all been cited as having the potential to help people live longer and better.
