Abstract:
DNA marker is commonly used to determine the size of DNA fragments by electrophoresis in routine molecular biology laboratories. In this study, we report a new procedure to prepare recombinant plasmids pSY-60 which was partially digested by one restriction enzyme for generating DNA markers of 7 fragments from 60 to 420 bp. The procedure included a synthesis of 60 bp DNA fragment with EcoRI sites at both ends using PCR extension, self-ligation of the 60 bp fragments and subcloning the ligated product into plasmid, generating recombinant pSY-60. Once being cloned, 500 ng of 420 bp fragment purif

These tests showed that a 98-bp 5′ fragment containing the 22-bp inverted repeat and four copies of the AAACCX (X = C, A, G) 5′ subterminal repeat is sufficient for transposition while a 52-bp 5′ fragment containing only one copy of the subterminal repeat is not.
