Multi-species Conserved Sequences

Multi-species Conserved Sequences

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 DNA...

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.

Sanger Sequencing

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...

Sequences

Sequences

Sequences are fundamental mathematical objects consisting of ordered lists of numbers that follow a specific rule or pattern. Sequences are critical in various mathematical concepts, including calculus, series, and number theory. They can model real-world phenomena such as population growth, financial investments, and physical processes like the diminishing height of a bouncing ball.Each number in a sequence is referred to as a term. Typically, the terms are denoted as a1, a2, a3,…, where the...

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 microarray-based...

Evolutionary Relationships through Genome Comparisons

Evolutionary Relationships through Genome Comparisons

Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Background:

High-throughput sequencing generates vast amounts of data, challenging existing bioinformatics analysis capabilities.
Current alignment tools often process sequencing reads sequentially, ignoring inherent redundancy.
Computational cost of genome analysis may become a bottleneck due to increasing sequencing throughput.

Purpose of the Study:

To develop a software package that mitigates the computational bottleneck in genome analysis.
To exploit redundancy in sequencing reads for faster alignment.
To improve the efficiency of bioinformatics pipelines for next-generation sequencing data.

Main Methods:

Developed Oculus, a software package that performs streaming compression, alignment, and decompression of input sequences.
Integrated Oculus with standard aligners to process redundant reads efficiently.
Evaluated performance across various datasets, measuring speedup and memory requirements.

Main Results:

Oculus achieved alignment speedups of up to 270% across diverse datasets.
The nearly lossless compression process (> 99.9%) maintained high fidelity of alignment output.
The software required a modest amount of memory, making it suitable for standard computational environments.

Conclusions:

Oculus efficiently condenses redundant reads, significantly reducing aligner runtime.
The software provides nearly identical SAM output compared to standard aligners.
Oculus is a versatile tool compatible with FASTA/FASTQ files and SAM format, with tunable performance options.
