Country Reports on Human Rights Practices are annual publications on the human rights conditions in countries and regions outside the United States, mandated by U.S. law to be submitted annually by the Bureau of Democracy, Human Rights, and Labor of the United States Department of State to the United States Congress.
Mitochondrial DNA is a small portion of the DNA contained in a eukaryotic cell; most of the DNA is in the cell nucleus, and, in plants and algae, the DNA also is found in plastids, such as chloroplasts. [3] Human mitochondrial DNA was the first significant part of the human genome to be sequenced. [4]
Identical mitochondrial DNA haplotypes S26 (AM43) and S13 (AM88) are expressed within both Siberian and Amerindian groups. "The S and AM designations represent the same haplotypes defined by the presence or absence of the specific restriction sites". [1] A path of separation would have lasted over a period of 15,000 to 40,000 years. [1]
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 as the "powerhouses" of the cell. Mitochondrial DNA (mtDNA) is not transmitted through nuclear DNA (nDNA).
This phylogenetic tree of haplogroup P subclades is based on the paper by Mannis van Oven and Manfred Kayser Updated comprehensive phylogenetic tree of global human mitochondrial DNA variation [2] and subsequent published research. P P-C16176T P1 P1d P1d1 P1d1a; P1d2 P1d2a; P1-T152C! P1f; P2'10 P2; P10; P8; P3 P3a; P3b P3b1; P4 P4a P4a1; P4b ...
The MT-ND4 gene is located in human mitochondrial DNA from base pair 10,760 to 12,137. [5] [11] The MT-ND4 gene produces a 52 kDa protein composed of 459 amino acids.[12] [13] MT-ND4 is one of seven mitochondrial genes encoding subunits of the enzyme NADH dehydrogenase (ubiquinone), together with MT-ND1, MT-ND2, MT-ND3, MT-ND4L, MT-ND5, and MT-ND6.
Studies of ancient DNA have found H5 in four individuals of around 6800 BC from the Pre-pottery Neolithic B site of Tell Halula, Syria. [6] H5a has been found in a Tagar (800 BC–100 AD) man on the Russian steppe whose Y-DNA was R1a1a [ 13 ] and in Margrethe , 11th century AD Queen of Denmark.
Human mitochondrial genome showing hypervariable regions I to III (green boxes) located in the control region (CR; grey box). There are two mitochondrial hypervariable regions used in human mitochondrial genealogical DNA testing. HVR1 is considered a "low resolution" region and HVR2 is considered a "high resolution" region.
