RNA-seq

RNA-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.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

Next-generation Sequencing

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.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features....

Area of Science:

Genomics
Bioinformatics
Molecular Biology

Background:

Repetitive genomic regions are crucial for organismal evolution, inheritance, and variation.
Existing repeat identification methods struggle with short next-generation sequencing (NGS) reads and high error rates in Single Molecule Sequencing (SMS) long reads.

Purpose of the Study:

To develop a novel framework, LongRepMarker, for precise identification of long genomic repeats.
To enhance the accuracy and comprehensiveness of repeat detection compared to current methods.

Main Methods:

Utilized barcode linked reads and SMS long reads to assist de novo assembly of short paired-end reads.
Employed k-mer based multiple sequence alignment to identify repeats by finding overlap sequences between assemblies or chromosomes.
Applied multi-alignment unique k-mers and a parallel alignment model for efficient and stable repeat identification.

Main Results:

LongRepMarker demonstrated superior performance in identifying repeats compared to existing de novo detection methods.
The framework accurately and comprehensively identified long repeats, overcoming NGS and SMS read limitations.
Enabled faster and more accurate repeat localization through overlap sequence analysis.

Conclusions:

LongRepMarker offers a robust and efficient solution for precise long repeat identification in genomes.
The method effectively addresses challenges posed by short reads and high error rates in sequencing data.
Facilitates deeper understanding of genomic evolution, inheritance, and variation through improved repeat analysis.
