Single strand as a template plus 3 prime end to start dna synthesis. a diagram shows a template strand of dna as a sequence of bases. on the 3 prime end is an oh. a 3-base primer is attached to the 3 prime end of the dna template via complementary base pairing; the 5 prime end of the primer lines up with the 3 prime end of the template dna. an oh is also on the 3 prime end of the primer. toward the 5 prime end of the dna template, polymerase works, and dna synthesis proceeds. the template dna sequence is (3 prime to 5 prime): g a a t c t g c t g; the primer attached to the three prime end of the template reads (5 prime to 3 prime): c t t. refer to the figure associated with this question. what bases will be added to the primer as dna replication proceeds? the bases should appear in the new strand in the order that they will be added starting at the 3' end of the primer.
