Abstract:
We formulated a method to synthesize 1 kbp DNA fragments using 'oligomer unidirectional joining method' via asymmetric extension supported by a simulator for oligonucleotide extension (AESOE). In this study, trials were conducted on 41 sets of different genomic pieces of ten flaviviral genomes, and 31 bacterial 16s rRNA fragments with sizes ranging from 500 bases to 1.0 kbp. Synthetic gene production was found to be successful in all those sets. The synthesis method has three steps: the first step is a seven-linked AESOE, the second step is the linking of the 400-base fragments from the first step, and the third step is the final amplification. Our present approach is highly reproducible and may no longer require optimization of oligomer design.

Lagging Strand Synthesis
There are several major differences between synthesis of the leading strand and synthesis of the lagging strand. 1) Leading strand synthesis happens in the direction of replication fork opening, whereas lagging strand synthesis happens in the...

The Replisome
The synthesis of the leading and lagging strands is a highly coordinated process. To explain this, the “Trombone model” was proposed by Bruce Alberts in 1980. The DNA loop formation starts when a primer is synthesized on the parent lagging strand. The loop grows with...
