Next-generation Sequencing

Next-generation Sequencing

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.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features.

Mismatch Repair

Mismatch Repair

Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
The Mutator Protein Family Plays a Key Role in DNA Mismatch Repair
The human genome has more than 3 billion base pairs of DNA per cell. Prior to cell division, that vast amount of genetic...

Maxam-Gilbert Sequencing

Maxam-Gilbert Sequencing

In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.

Sanger Sequencing

Sanger Sequencing

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...

Molecular Biology

Background:

High-throughput sequencing enables versatile DNA and RNA research.
Multiplexing DNA samples requires unique barcodes for sample identification.
Errors in DNA barcodes can lead to misidentification, necessitating error correction.

Purpose of the Study:

To address the limitations of traditional Levenshtein codes in DNA sequencing.
To develop an adapted Levenshtein code for efficient DNA barcode error correction.
To improve the accuracy and efficiency of multiplexed DNA sequencing.

Main Methods:

Adapted Levenshtein codes to account for DNA sequence characteristics.
Redefined word length dynamically to handle insertions and deletions.
Simulated performance against traditional Levenshtein and Hamming codes.

Main Results:

Demonstrated decreased error correction capability of classical Levenshtein codes in DNA.
Showcased superior error correction of the adapted Levenshtein codes in simulations.
Validated the method's ability to correct nucleotide errors, insertions, and deletions.

Conclusions:

An adapted Levenshtein code effectively corrects DNA barcode mutations (insertions, deletions, substitutions).
The improved method recovers codeword length and corrects more mutations than traditional codes.
Developed software for flexible DNA code generation, user-customizable for experimental needs.
