Human Cloning Projects

Large quantities of each clone can be grown for DNA sequencing studies, similar to what is being done in the Human Genome Project. 

In the eighth decade of his life, Berg remains active both as a researcher and as an advocate for the scientific community at the state and federal levels. In addition to serving as chair of the scientific advisory committee of the Human Genome Project, he has spoken and written in support of federal and state financing for stem cell research, human cloning, and other forms of biotechnology. 

With completion of the human genome project, the functional and positional cloning of Mendelian traits and diseases can become fairly routine (2). Yet, considerable work still lies ahead even with Mendelian diseases document worldwide variation in mutations, identify the effects of modifier genes on heterogeneity with respect to age of onset and severity, obtain accurate measurements of the penetrance values of different allelic mutations, study the effects of environmental factors on disease expression, and develop appropriate therapies. 

Some of the more spectacular uses of PCR include cloning of ancient DNA from extinct species such as the woolly mammoth ruling out suspects in criminal cases by forensic science, and providing genomic markers (STSs) in chromosome-mapping studies used in the Human Genome Project (see Chapter 21).
