  2. Human mitochondrial genetics - Wikipedia

    en.wikipedia.org/wiki/Human_mitochondrial_genetics

    Human mitochondrial genetics is the study of the genetics of human mitochondrial DNA (the DNA contained in human mitochondria). The human mitochondrial genome is the entirety of hereditary information contained in human mitochondria. Mitochondria are small structures in cells that generate energy for the cell to use, and are hence referred to ...

  3. Mitochondrion - Wikipedia

    en.wikipedia.org/wiki/Mitochondrion

    In general, mitochondrial DNA lacks introns, as is the case in the human mitochondrial genome; [144] however, introns have been observed in some eukaryotic mitochondrial DNA, [146] such as that of yeast [147] and protists, [148] including Dictyostelium discoideum. [149] Between protein-coding regions, tRNAs are present.

  4. Mitochondrial DNA - Wikipedia

    en.wikipedia.org/wiki/Mitochondrial_DNA

    Human mitochondrial DNA was the first significant part of the human genome to be sequenced. [4] This sequencing revealed that human mtDNA has 16,569 base pairs and encodes 13 proteins. As in other vertebrates, the human mitochondrial genetic code differs slightly from nuclear DNA. [5]

  5. Mitochondrial Eve - Wikipedia

    en.wikipedia.org/wiki/Mitochondrial_Eve

    In human genetics, the Mitochondrial Eve (more technically known as the Mitochondrial-Most Recent Common Ancestor, shortened to mt-Eve or mt-MRCA) is the matrilineal most recent common ancestor (MRCA) of all living humans. In other words, she is defined as the most recent woman from whom all living humans descend in an unbroken line purely ...

    The hypothetical woman at the root of all these groups (meaning just the mitochondrial DNA haplogroups) is the matrilineal most recent common ancestor (MRCA) for all currently living humans. She is commonly called Mitochondrial Eve. The rate at which mitochondrial DNA mutates is known as the mitochondrial molecular clock. It is an area of ...

    Mitochondria play a vital role in cellular energy production, metabolism, and immune response. By understanding how mitochondrial dysfunction contributes to Crohn’s disease, researchers can ...

  8. Mitochondrial disease - Wikipedia

    en.wikipedia.org/wiki/Mitochondrial_disease

    Mitochondrial disease is a group of disorders caused by mitochondrial dysfunction. Mitochondria are the organelles that generate energy for the cell and are found in every cell of the human body except red blood cells. They convert the energy of food molecules into the ATP that powers most cell functions.

  9. Extranuclear inheritance - Wikipedia

    en.wikipedia.org/wiki/Extranuclear_inheritance

    The father's mitochondrial genes are not transmitted to the offspring via the sperm. Very rare cases which require further investigation have been reported of paternal mitochondrial inheritance in humans, in which the father's mitochondrial genome is found in offspring. [6] Chloroplast genes can also inherit uniparentally during sexual ...
