RNA-seq03:21

RNA-seq

10.5K
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...

Multi-species Conserved Sequences

4.3K
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale  studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...

Sanger Sequencing

761.7K
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

94.2K
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....

Maxam-Gilbert Sequencing

11.7K
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.

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Data Science

Background:

  • Existing sequence formats like FASTA have limitations in representing complex biological data.
  • Custom alphabet formats offer some flexibility but lack broad applicability.
  • There is a need for a more general sequence file format to handle diverse linear stream data.

Purpose of the Study:

  • To define a novel sequence file format, FASTC (Flexible Alphabet Sequence Tagged Code), capable of handling multi-character elements.
  • To create a format that is more general and versatile than existing FASTA or custom alphabet formats.
  • To provide a standardized method for representing various types of sequence data for advanced analyses.

Main Methods:

  • The FASTC format is derived from principles of the FASTA format and the POY4/5 custom alphabet format.
  • FASTC allows for the definition and use of multi-character elements within sequence data.
  • The format is designed to be applicable to datasets encoded as linear streams.

Main Results:

  • The proposed FASTC format successfully accommodates multi-character elements, offering greater flexibility than traditional formats.
  • FASTC can represent a broad spectrum of sequence-type data, including but not limited to biological sequences.
  • The format is demonstrated to be suitable for complex analytical tasks.

Conclusions:

  • FASTC provides a generalized and powerful solution for representing diverse sequence data.
  • This format is expected to be highly beneficial for various research areas, including comparative genomics, developmental biology, and behavioral studies.
  • The adoption of FASTC can streamline analyses involving complex, time-series, or multi-faceted linear datasets.
