Resumen
La secuenciación de lectura larga (LRS) supera las limitaciones de las lecturas cortas en metagenómica al permitir la reconstrucción completa del genoma. Esta revisión detalla los avances computacionales para LRS, mejorando el análisis de comunidades microbianas.
Área de la Ciencia:
- Microbiología
- Genómica
- Bioinformática
Sus antecedentes:
- La secuenciación de metagenómica de próxima generación (mNGS) que utiliza lecturas cortas tiene dificultades con las regiones repetitivas, lo que provoca ensamblajes fragmentados de genomas microbianos.
- Esta fragmentación dificulta el análisis exhaustivo de la composición, función y elementos genéticos microbianos.
Objetivo del estudio:
- Proporcionar una visión general sistemática de los enfoques computacionales para la metagenómica de lectura larga (LRS).
- Destacar los avances en LRS para la caracterización del genoma microbiano y el análisis de comunidades.
Principales métodos:
- Revisión de estrategias computacionales para datos LRS.
- Enfoque en el perfilado taxonómico, ensamblaje y agrupamiento de genomas, y detección de elementos genéticos.
- Discusión de aplicaciones LRS en la detección de variaciones estructurales y la identificación de patrones de metilación.
Principales resultados:
- Las tecnologías LRS (PacBio, Oxford Nanopore) permiten la reconstrucción continua del genoma al abarcar regiones repetitivas.
- Las mejoras computacionales mejoran la clasificación taxonómica de alta resolución y la recuperación de elementos genéticos esenciales.
- LRS facilita la caracterización detallada de cepas y la detección de variaciones estructurales.
Conclusiones:
- LRS, junto con métodos computacionales avanzados, ofrece un potencial transformador para la ecología microbiana.
- Es posible una mejor comprensión de la diversidad, funciones e interacciones microbianas con LRS.

RNA-seq
12.2K
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...

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.

Maxam-Gilbert Sequencing
13.0K
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.

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...

Genome Annotation and Assembly
21.1K
The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.
