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...

RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while microarray-based...

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...

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...

Genome Annotation and Assembly

Genome Annotation and Assembly

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.

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.

Background:

Deoxyribonucleic acid (DNA) molecular recognition relies on complementary base pairing, fundamental to genetics, DNA nanotechnology, and DNA computing.
Existing DNA sequence design methods have limitations in generating large sets of sequences with specific properties.

Purpose of the Study:

To develop an exhaustive algorithm for designing nucleic acid sequences with precisely controlled properties.
To create a software tool, EGNAS, for efficient and comprehensive DNA sequence generation.

Main Methods:

Implemented an exhaustive algorithm in a C++ program named EGNAS (Exhaustive Generation of Nucleic Acid Sequences).
Enabled control over interstrand and intrastrand properties, including guanine-cytosine content, start/end bases, and avoidance of fraying.
Allowed limiting cross-hybridizations, adjusting sequence uniqueness, and forbidding specific sequences or subsequences.
Facilitated designing sequences with minimal interactions with predefined strands and neighboring sequences.

Main Results:

EGNAS generates maximal sets of sequences under defined constraints, outperforming previous software.
The software supports the generation of TAG sequences for multiplexed genotyping and primer design, limiting foldback.
Demonstrated sequence design for specific attachment of molecular constructs to DNA origami.

Conclusions:

EGNAS is a novel software tool for designing unique nucleic acid sequences.
The exhaustive algorithm allows for the generation of larger sequence sets compared to existing software under identical constraints.
EGNAS is freely available for non-commercial use.
