Gene Synthesis Methods- A Synopsis

The chemical synthesis of a strand of DNA base by base is referred to as gene synthesis. Gene synthesis, unlike DNA replication in cells or by Polymerase Chain Reaction (PCR), does not require a template strand. Gene synthesis, on the other hand, entails the sequential addition of nucleotides to a single-stranded molecule, which subsequently serves as a template for the formation of a complementary strand. The area of synthetic biology was founded on the core technology of gene synthesis.

Any DNA sequence, including sequences that do not exist in nature or variants on naturally occurring sequences that would be difficult to create through site-directed mutagenesis, can be synthesized. Synthetic DNA can be cloned into expression vectors and used in any procedure where natural or recombinant DNA is required. Synthetic genes are utilized to study all of nucleic acids' biological functions, from encoding proteins and controlling gene expression in the nucleus to mediating cell-cell communication and forming biofilms out of extracellular DNA.

How is Gene Synthesis Performed?

Gene synthesis methods cannot be substituted for one another, and each has its own niche depending on the project's needs. The following is a quick rundown of some of the most frequent gene synthesis techniques:

Synthesis in the solid state

A small volume of fluid is treated in a column full of chemicals in classic oligonucleotide synthesis. The oligonucleotides are made by one-by-one adding nucleotide residues to the end of the chain. De-blocking, coupling, capping, and oxidation are the four processes in the addition of each oligonucleotide. For products longer than 200bp, the sequence integrity and synthesis productivity are hampered, hence this approach is often limited by DNA sequence length. The main benefit of this technology is its great accuracy, which offsets its expensive cost and poor output.

DNA synthesis on a chip

Chip-based synthesis, as the name suggests, makes use of microarray chips and a variety of electrochemical processes. Different types of oligonucleotides can be generated in different portions of the chips, which are referred to as assembly subpools. Gene fragments in subpools are amplified after this piecewise synthesis, then aggregated and assembled into the completed product. Chip-based DNA synthesis is less expensive than solid-phase synthesis and can produce more of the target gene.

PCR based enzyme synthesis

Gene fragments are generated using PCR-based enzyme synthesis in a variety of cell systems. Employing the Yeast system as an example, different types of genes can be inserted to Yeast chromosomes by using different incision enzymes and label markers. Because of the nature of gene insertion, the target gene could be as lengthy as the chromosomes will allow it to be. This approach works well for synthesizing big gene fragments, and the precision of the gene sequence is ensured thanks to the use of cell systems.
