Summary
We developed a new gene synthesis method using Data-optimized Assembly Design (DAD) and Golden Gate Assembly. This approach rapidly produces codon-optimized genes, enabling broader sequence construction than traditional methods.
Area of Science:
- Synthetic Biology
- Molecular Biology
- Gene Synthesis
Background:
- Commercial gene synthesis often relies on homology-based cloning.
- Existing methods like polymerase cycling assembly have limitations in sequence breadth.
Purpose of the Study:
- To apply Data-optimized Assembly Design (DAD) for efficient gene synthesis.
- To utilize Golden Gate Assembly for constructing codon-optimized genes in various vectors.
Main Methods:
- Genes were synthesized from oligonucleotide pools in three steps: part amplification, Golden Gate Assembly, and transformation.
- Data-optimized Assembly Design (DAD) guided the assembly process.
- T4 DNA ligase was used for high-ligation fidelity.
Main Results:
- Hundreds of codon-optimized genes were synthesized rapidly, with sequence-confirmed isolates in as little as 4 days.
- The method demonstrated efficiency in both constitutive and inducible vectors.
- The approach is expected to support a wider range of sequences compared to homology-based methods.
Conclusions:
- DAD combined with Golden Gate Assembly provides a fast and efficient method for gene synthesis.
- This technique expands the possibilities for constructing diverse gene sequences.
- The method offers an alternative to traditional gene synthesis approaches with improved capabilities.

18.8K
The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.

DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.

01:24DNA Isolation
39.1K
DNA isolation protocols can be fast and straightforward or complex and time-consuming depending on the type and quality of DNA required for further processing. For example, plasmid DNA extraction is a bit more complicated than genomic DNA extraction because of the need for an appropriate lysis method to separate plasmid DNA from gDNA during isolation. However, for specific applications, such as long-range DNA sequencing that require a good yield of high- quality DNA samples, we need to follow...
