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.
Recombinant DNA is one of the core techniques of genetic engineering. It is the process of removing DNA from one organism and inserting it into the DNA of another organism, giving it new traits. Recombinant DNA can be used to make crops resistant to pests or disease, it can be used to make livestock leaner or larger.In medicine, the technique can be used to develop drugs, vaccines, and to reproduce important human hormones and proteins.By engineering human DNA into a host organism, that organism can be turned into a factory for important medical products. Insulin production is an excellent example of the recombinant DNA process.n medicine, the technique can be used to develop drugs, vaccines, and to reproduce important human hormones and proteins.
