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...

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.

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...

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....

Epigenetics
Genomics
Molecular Biology

Background:

DNA methylation is crucial in prokaryotic and eukaryotic gene regulation.
Prokaryotes exhibit three main DNA methylation forms: N⁶-methyladenine (6mA), N⁴-methylcytosine (4mC), and 5-methylcytosine (5mC).
Existing sequencing technologies often struggle to map multiple methylation types concurrently.

Purpose of the Study:

To introduce NT-seq, a novel sequencing technology.
To enable simultaneous detection and mapping of all three major prokaryotic DNA methylation types.
To provide an efficient tool for analyzing DNA methylation patterns.

Main Methods:

Development and application of the NT-seq method.
Genomic DNA sequencing and methylation analysis.
Validation in two bacterial genomes.

Main Results:

NT-seq successfully mapped all three DNA methylation types (6mA, 4mC, 5mC) simultaneously.
The method reliably detected known methylation motifs in bacterial genomes.
NT-seq demonstrated capability in identifying de novo methylation motifs.
The technology offers a simple and efficient solution for multi-type DNA methylation detection.

Conclusions:

NT-seq is an effective tool for comprehensive DNA methylation analysis in prokaryotes.
This method advances the study of epigenetic regulation by enabling simultaneous mapping of multiple methylation marks.
NT-seq provides a valuable solution for researchers investigating prokaryotic epigenomes.
