Abstract
An improved means for amplifying DNA sequences is disclosed. The invention provides a means for creating tandemly repeated gene sequences. One attaches a selected foreign gene sequence in a S. achromogenes fragment and then exposes the recombinant segment to antibiotic challenge. Temperature sensitive plasmids or other curable vectors can be used to assist in the amplification and the positioning of the resulting gene directly in chromosomal host DNA.
