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 use of biological evidence in DNA and genetic analysis varies, with areas of study including blood typing, gender determination based on chromosome analysis (karyotyping), DNA profiling and, more recently, forensic DNA phenotyping.n the analysis of SNPs, which can consist of up the four alleles, the specific base present in the SNP must be established. This is achieved using DNA sequencing techniques. However DNA sequencing is not generally used in forensic science except in the analysis of mitochondrial DNA.
