Summary
Synthesizing repetitive DNA sequences is challenging. This new method uses Golden Gate assembly to build synthetic genes from smaller DNA fragments, overcoming synthesis limitations.
Area of Science:
- Molecular Biology
- Synthetic Biology
- Biotechnology
Background:
- Recent advancements have improved gene synthesis efficiency.
- Challenges persist with synthesizing repetitive DNA sequences, leading to vendor delays or failures.
Purpose of the Study:
- To describe a novel method for assembling synthetic genes containing repetitive elements.
- To overcome limitations in current DNA synthesis technologies for repetitive sequences.
Main Methods:
- In silico gene fragmentation into synthons (up to 80 bp) with Golden Gate-compatible overhangs.
- Synthon generation via oligo extension.
- Assembly of synthons into the final synthetic gene using Golden Gate assembly.
Main Results:
- Successfully assembled small synthetic genes with repetitive elements.
- Demonstrated a viable method to circumvent common gene synthesis bottlenecks.
Conclusions:
- The described Golden Gate assembly approach provides an effective strategy for constructing synthetic genes with repetitive sequences.
- This method enhances the feasibility and efficiency of synthesizing challenging DNA constructs.

6.3K
Rapid Amplification of cDNA Ends, or RACE, is one of the most effective methods to obtain a full-length cDNA from an mRNA sequence between a known internal region to the unknown sequence at the 5’ or 3’ end. The unknown region is cloned in the cDNA by a gene-specific primer that binds the known end, and a hybrid primer that attaches a predefined anchor sequence to the unknown end of the cDNA. The sequence in between is amplified by PCR with an anchor primer and a gene-specific...

88.4K
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.

03:36Genome Annotation and Assembly
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.
