PCR reactions are specific to particular pieces of DNA. Which component of the reaction allows for this specificity? Explain how.


Sanger Sequencing (also called chain termination and dideoxy-sequencing) utilizes special dideoxy nucleotides (ddNTPs). What is the difference between these special nucleotides and the dNTPs used in PCR?

What role do the ddNTPs play in the sequencing reaction?
