(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.
Cultured 1) Ecoli with 32P (for DNA) and 2) Ecoli with 35S (for protein). Used these cultures to produce T2 with 32P or 35S. These then infected normal Ecoli. Hershey and Chase: What they found. After lysis of phage ghosts off pf Ecoli cells, 32P (DNA) was found in the progeny phages, but 35S (protein) found in the phage ghosts. Hershey and Chase: What it meant. DNA must be the material responsible for function and reproduction of phage T2. T2. Bacteriophage consisting of only DNA and protein.
