Summary
Nanopore sequencing offers a revolutionary method for analyzing DNA and RNA at the single-molecule level. This technology enables rapid, low-cost genome sequencing without amplification, paving the way for advanced genetic analysis.
Area of Science:
- Biotechnology
- Genomics
- Analytical Chemistry
Background:
- Nanopore devices enable single-molecule detection and analysis by passing molecules through a nano-scale pore.
- This confined space allows for high-throughput analysis of nucleic acid polymers and small molecules.
Purpose of the Study:
- To highlight the capabilities of nanopore-based devices for molecular analysis.
- To discuss the potential for rapid and inexpensive DNA sequencing.
Main Methods:
- Electrophoretic driving of molecules through a nano-scale pore.
- Detection and analysis of single nucleic acid polymers and small molecules within the pore.
Main Results:
- Nanopore analysis allows identification and characterization of kilobase-length polymers (DNA/RNA) and nucleosides without amplification or labeling.
- The native order of nucleobases is accurately reflected in detected signals due to controlled processivity.
Conclusions:
- Nanopore technology presents a unique analytical capability for cost-effective, rapid DNA sequencing.
- Further development promises 'third generation' instruments capable of sequencing a mammalian genome in approximately 24 hours for around $1,000.

03:21RNA-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.

03:00Next-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.

01:57Sanger 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...
01:05Maxam-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.
