RNA-seq

9.2K
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...

Maxam-Gilbert Sequencing

10.3K
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

87.4K
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

800.2K
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
  • Genomics

Background:

  • Standard high-throughput sequencing (HTS) data analysis often relies on existing tools.
  • Custom scripting becomes necessary for non-standard HTS data analysis workflows.

Purpose of the Study:

  • To introduce HTSeq, a Python library designed for efficient custom script development in HTS data analysis.
  • To provide essential components for handling diverse HTS data formats and genomic information.

Main Methods:

  • Development of a Python library (HTSeq) with parsers for common HTS data formats.
  • Implementation of classes for representing genomic data (coordinates, sequences, reads, alignments, gene models, variant calls).
  • Inclusion of data structures enabling genomic coordinate-based querying.

Main Results:

  • HTSeq facilitates rapid development of custom scripts for HTS data analysis.
  • The library supports various genomic data types and provides efficient querying capabilities.
  • The associated tool, htseq-count, preprocesses RNA-Seq data for differential expression analysis by quantifying read-gene overlaps.

Conclusions:

  • HTSeq offers a flexible and powerful solution for researchers needing custom HTS data analysis tools.
  • The library and its associated tools streamline complex bioinformatics workflows, particularly for RNA-Seq analysis.
