Biology: Ch. 20 Study Guide Explain how advances in recombinant DNA technology have helped scientists study the eukaryotic genome. In short: Recombinant DNA has allowed the creation of the biotechnology industry. Longer explanation: Recombinant DNA is DNA in which nucleotide sequences from two different sources ? often different species ? are combined in vitro into the same DNA molecule. Once created by scientists, it is introduced into cultured cells that replicate the DNA and express its genes, creating a desired protein product. This has allowed genetic engineering (the direct manipulation of genes for practical purposes), which has created the biotech industry. Explain the goals of the Human Genome Project.
