Comparison of DNA sequences across populations helped with this task. Currently, scientists continue to work on perfecting the sequence, correcting the errors that occur, on average, about once ...

In simple terms, replication involves use of an existing strand of DNA as a template for the synthesis of a new, identical strand.

Based on these findings, the scientists worked with Medical and Biological Laboratories Co., Ltd. to develop a DNA sequencing kit for codon 139 that produces accurate results within two hours.
