#Section 7: Recombinant DNA technology and Other Tools in Biotechnology

In order to quantify unknown DNA templates, a standard dilution is prepared using DNA of known concentration. As the DNA accumulates during the early exponential phase of the reaction,an arbitrary point is taken where each of the diluted DNA samples cross. This is termed as_____
