The difference between an element and a compound is that an element is a substance made of same type of atoms, whereas a compound is made of different elements in definite proportions.
(July 2010). Molecular anthropology is a field of anthropology in which molecular analysis is used to determine evolutionary links between ancient and modern human populations, as well as between contemporary species.itochondrial DNA offers another advantage over autosomal DNA. There are generally 2 to 4 copies of each chromosome in each cell (1 to 2 from each parent chromosome). For mtDNA there can be dozens to hundreds in each cell.
The mitochondrial DNA analysis technique uses DNA that is extracted from the mitochondrion. STR analysis uses DNA from the cellâs nucleus. Typically, mtDNA is used to extract DNA from old evidence like hair, teeth and bones that no longer has any nucleic DNA material to use for STR analysis. The mtDNA analysis process is extremely beneficial in helping to solve cold cases and unidentified remains.
