Abstract:DNA sequencing using reversible terminators, as one sequencing by synthesis strategy, has garnered a great deal of interest due to its popular application in the second-generation high-throughput DNA sequencing technology. In this review, we provided its history of development, classification, and working mechanism of this technology. We also outlined the screening strategies for DNA polymerases to accommodate the reversible terminators as substrates during polymerization; particularly, we introduced the “REAP” method developed by us. At the end of this review, we discussed current limitations of this approach and provided potential solutions to extend its application.
Keywords:DNA polymerases  Sequencing technology  Modified nucleotide  Primer extension  Reversible terminator  Sequencing by synthesis
