DNA sequencing

Consider the following DNA sequencing experiment: 3′ —– GATACCGCTA-5′ (template)
5′ primer. In this setup, DNA polymerase will place a C just after the primer and across from the G in the template strand, and additional bases will be added in the usual manner. Four separate reactions will be run, and each will contain all four dNTPs; however, the “A” experiment will contain, in addition to the four dNTPs, a small amount of ddATP; the “G’ experiment will contain all four dNTPs and a small amount of ddGTP, and so on. Given this information, when a sample from the “G” experiment is run on a gel, what will be the sequence (5′ to 3′) of the smallest complementary strand?
