A) DNA polymerase binds to a single-stranded DNA template (blue) and synthesizes a complementary ... From these data, the sequence of the newly synthesized DNA strand is determined, as shown ...

At this point, the target sequence is exposed to a solution that contains DNA polymerase and all of the nucleotides required for synthesis of the complementary DNA strand — along with one ...

When a gene is to be expressed, the base sequence of DNA is copied ... form hydrogen bonds with the exposed DNA strand nucleotides by complementary base pairing to form a strand of mRNA: Note ...
