Summary
VNTRseek software discovers minisatellite variable number tandem repeats (VNTRs) using whole genome sequencing. This tool identifies VNTRs across diverse genomes, enabling new insights into genomic variation and inheritance patterns.
Area of Science:
- Genomics
- Bioinformatics
- Molecular Biology
Background:
- DNA tandem repeats (TRs) are repetitive sequences in genomes.
- Variable number tandem repeats (VNTRs) are polymorphic TRs with varying copy numbers.
- Minisatellite VNTRs have pattern sizes of 7 nucleotides or more.
Purpose of the Study:
- To introduce VNTRseek, a novel software for detecting minisatellite VNTRs.
- To enable genome-wide discovery of VNTRs using whole genome sequencing data.
Main Methods:
- VNTRseek maps sequencing reads to reference TRs.
- It identifies VNTRs by comparing read copy numbers to reference copy numbers.
- The software was tested on Watson, Khoisan, and 1000 Genomes family trio genomes.
Main Results:
- VNTRseek identified 752 VNTRs in the Watson genome (7-84 nt patterns).
- It detected 2572 VNTRs in the Khoisan genome (7-105 nt patterns).
- In trios, 2660-3822 VNTRs per individual were found with high Mendelian inheritance consistency.
Conclusions:
- VNTRseek is the first software for genome-wide minisatellite VNTR detection.
- The software facilitates the study of VNTRs in various genomic contexts.
- VNTRseek is publicly available for research use.

Peptide Identification Using Tandem Mass Spectrometry
6.2K
Tandem mass spectrometry, also known as MS/MS or MS2, is an analytical technique that employs two mass analyzers. Essentially it is a series of mass spectrometers that helps isolate a particular biomolecule and then helps study its chemical properties.
This technique helps gather information regarding the protein from which the peptide was obtained and to study the peptides’ amino acid sequence. Identifying peptides from a complex mixture is an important component of the growing field of...

Tandem Mass Spectrometry

Tandem mass spectrometry is a technique that uses multiple mass analyzers in series to obtain a higher selectivity and reduce chemical noise during analyte detection. Instruments with multiple analyzers separated by an interaction cell enable secondary fragmentation and selected study of the fragment ions.Secondary fragmentations occur in the interaction cell and can be induced by various factors. Fragmentation induced by collision with inert gases, such as N2, Ar, He, etc., is called...

Comparing Copy Number Variations and SNPs
11.5K
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Next-generation Sequencing
87.6K
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.

RNA-seq
9.2K
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...

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...
