nt of DNA. What color is the primer in the following diagram? Red Purple Blue - correct answer Red Feedback Recall from the section on DNA replication that DNA polymerase needs a primer to begin DNA synthesis. This requirement means the primers will direct the DNA polymerase to only synthesize complementary strands of the target DNA. (Note: In DNA replication, the primers are RNA primers, while PCR generally uses DNA primers because they are more stable.) dNTPs are DNA nucleotides use...
