WebSanger chain termination sequencing differs from polymerase chain reaction because: A. only one primer is used. B. DNA polymerase is not needed. C. the process is isothermal. D. only three nucleotide bases are used. WebSanger sequencing was developed in 1977, and it was based on selective “chain termination” reactions occurring via in vitro DNA replication by DNA polymerase. This is achieved by the introduction of dideoxynucleotides (ddNTPs) in the replication reaction. Four types of ddNTPs are used, one for each nucleotide (ddATP, ddGTP, ddCTP, and ddTTP).
