  • Dye- primer sequencing facilitates reading in an optical system for faster and more economical analysis and automation. (michaelperes.com)
  • Limitations include non-specific binding of the primer to the DNA,affecting accurate read-out of the DNA sequence,and DNA secondary structures affecting the fidelity of the sequence. (michaelperes.com)
  • Dye-terminator sequencing utilizes labelling of the chain terminator ddNTPs,which permits sequencing in a single reaction,rather than four reactions as in the labelled- primer method. (michaelperes.com)
