Then the DNA clone can be electronically lab...

There, scientists quickly realized that observing the human genome could be useful in discovering environmental mutates. Shortly afterwards, Renato Dulbecco revealed the entire sequence of human DNA and had a great impact on cancer research (Purves, et al. 1998). In 1990, scientists from around the world began the Huma...
