Maxam-Gilbert Sequencing01:05

Maxam-Gilbert Sequencing

10.5K
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.

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.

Sanger Sequencing

800.8K
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...

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Genetics

Background:

  • Decryption of doubly heterozygous sequences (DHS) is crucial for indel mutation reporting.
  • Traditional methods require reference sequences and specialized software.
  • A novel approach using number-based algorithms can overcome these limitations.

Purpose of the Study:

  • To develop and evaluate a novel algorithm for decrypting DHS without a reference sequence.
  • To enable efficient indel mutation reporting in clinical settings.
  • To facilitate accurate alignment of multiple overlapping sequence reads.

Main Methods:

  • Converted the DNA sequence from a 4-letter genetic code to a 4-prime-number code (A=2, C=3, G=5, T=7).
  • Developed the PrimeIndel algorithm utilizing the greatest common divisor (GCD) of prime-number coded sequences to identify overlapped nucleotides.
  • Applied the algorithm for in-silico DHS formation and alignment of sequence reads.

Main Results:

  • Successfully decrypted DHS using the prime number-based algorithm.
  • Achieved correct alignment of multiple overlapping sequence reads.
  • Demonstrated the algorithm's effectiveness in defining indel mutations.

Conclusions:

  • DNA sequences represented by prime numbers can be effectively decrypted using GCD mathematical functions.
  • PrimeIndel offers a practical and efficient tool for mutation reporting in clinical laboratories.
  • The PrimeIndel software is publicly available for download.
