DNA polymerase moves along the length of the unwound helix, starting at the end of one strand and finishing at the end of the other strand. As shown in this figure, what is the result of this phenomenon?
A). The DNA polymerase moves toward the unwound helix on one strand of DNA arid away from it on the other strand. 

B). Free nucleotides are added to one strand of parental DNA but not to the other. 

C) One resulting double strand of DNA is composed of new DNA, and one is composed of parental DNA. 

D). DNA polymerase is destroyed as it binds nucleotides to form each daughter strand.
