The reaction is continued until the desired chain length is reached. About 70–80 residue polymers can be made this way. The process has also automated versions and routine synthetic services are commercially available. (Linkletter BA et al 2001 Nucleic Acids Res 29:2370)...
Then, the excess free nucleotide is removed by washing, and the protective group is then removed under a chemical reaction. The following nucleotides are added one after the other in repeated cycles. In contrast, enzymatic synthesis was invented in the early 2010s and relied on the unique role...

2B) that, after initially created via chemical synthesis, were cloned into plasmids and continually replicated in bacteria as needed. The orthogonality and modularity of the DMOS system allow for efficient bit-level writing and reading We tested whether the modular DMOS writer system using dCas9 ...
The addition of a single nucleotide requires four chemical reactions with washings between each reaction. Each cycle of reactions and washings takes about 12 minutes. When the synthesis is complete, the protecting groups are removed and the chains freed from the solid support. While addition of ...
This helps keep the activity of the DNA polymerase low, but synthesis of undesirable products may still occur before the start of PCR. Another solution is to delay adding the DNA polymerase until the annealing step of the first...
because these concepts give the necessity of the existence of DNA helicase. Semi retained replication of DNA refers to the disassembly of double strands of DNA, the retention of one strand, and the new synthesis of another strand. In other words, the newly synthesized DNA contains a mother cha...

This mechanism has recently been captured directly by a detailed structural study of the DNA synthesis reaction by the error-prone human DNA polymerase η [214]. The thumb domain contacts the nascent dsDNA upstream of the active site. The extended fingers domain, adjacent to the palm, ha...
The mechanism of DNA synthesis has been inferred from static structures, but the absence of temporal information raises longstanding questions about the order of events in one of life’s most central processes. Here we follow the reaction pathway of a replicative DNA polymerase using time-resolved ...
