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...

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.

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

Evolutionary Relationships through Genome Comparisons

Evolutionary Relationships through Genome Comparisons

Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

DNA as a Genetic Template

DNA as a Genetic Template

Two structural features of the DNA molecule provide a basis for the mechanisms of heredity: the four nucleotide bases and its double-stranded nature. The Watson-Crick model of double-helical DNA structure, proposed in 1952, drew heavily upon the X-ray crystallography work of researchers Rosalind Franklin and Maurice Wilkins. Watson, Crick, and Wilkins jointly received the Nobel Prize in Physiology or Medicine for their work in 1962. Franklin was, controversially, excluded from the prize for...

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.

Background:

DNA computing utilizes DNA molecules for information storage and biological interactions for processing.
Controlling molecular reactions is crucial for accurate computations in DNA-based systems.
Designing reliable DNA libraries for bio-molecular computing is an NP-hard problem with conflicting criteria.

Purpose of the Study:

To design and generate reliable DNA libraries for computational applications.
To model DNA sequence design as a multi-objective optimization problem.
To address the challenges of heterogeneous and conflicting design criteria.

Main Methods:

An adapted multi-objective version of the differential evolution (DE) metaheuristics was employed.
Seven distinct bio-chemical design criteria were simultaneously optimized.
A comparative study utilized the multi-objective standard fast non-dominated sorting genetic algorithm (NSGA-II) and literature results.

Main Results:

The DE metaheuristics successfully generated high-quality DNA sequences suitable for molecular computing.
The proposed approach significantly improved upon existing DNA libraries.
The method demonstrated its capability in handling complex, multi-objective design constraints.

Conclusions:

The adapted multi-objective DE metaheuristics offer a promising approach for designing reliable DNA libraries.
This method effectively addresses the NP-hard nature of DNA sequence design for bio-molecular computing.
The generated DNA sequences show superior performance compared to previously published libraries.
