RNA-seq

12.6K
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...

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

101.5K
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....

Advancements in molecular biology have revolutionized the identification and characterization of bacteria, with multiple methods leveraging DNA sequencing for enhanced precision. As sequencing technologies improve and costs decline, these approaches are increasingly used in clinical, environmental, and evolutionary studies.Multilocus Sequence Typing (MLST) examines several housekeeping genes, essential chromosomal genes encoding cellular functions, to distinguish strains. Approximately...

  • Bioinformatics

Background:

  • DNA sequencing is the gold standard for genetic analysis, primarily used for validation and reference.
  • Direct application of sequencing for sample characterization, especially for mixed genomes, has faced skepticism.
  • All biological samples and isolates comprise populations of genomes.

Purpose of the Study:

  • To present and review the utility of direct DNA sequencing for identifying multiple genomes within samples.
  • To introduce and validate the Population-Sequencing approach for comprehensive sample characterization.

Main Methods:

  • Utilizing probabilistic matching tools with large-scale sequence data for genome identification.
  • Analyzing DNA across entire genomes to assign genome presence and calculate confidence scores for major and minor components.
  • Directly analyzing millions of DNA fragments from mixtures without culture purification.

Main Results:

  • Accurate genome identification from complex mixtures is achievable through direct DNA analysis.
  • Population-Sequencing enables phylogenetic classification of genomes within samples.
  • This method allows for the establishment of detailed sample profiles, including rare genetic variants and relatedness between samples.

Conclusions:

  • Direct use of sequencing, termed Population-Sequencing, offers a powerful strategy for characterizing sample genomes.
  • This approach facilitates accurate genome identification, phylogenetic classification, and detailed sample profiling.
  • Population-Sequencing enhances genetic analysis by enabling identification of major and minor genome components and rare genetic events.
