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...

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...

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...

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...

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Area of Science:

Genomics
Bioinformatics
Computational Biology

Background:

Repetitive elements (REs) form species-specific RE arrays in human and mouse genomes.
Understanding the organization and distribution of REs is crucial for genomic research.

Purpose of the Study:

To develop and evaluate REViewer, a novel bioinformatics tool for visualizing RE occurrences.
To facilitate the analysis of RE arrays and other genomic regions.

Main Methods:

Developed REViewer, an interactive line map visualization tool.
Utilized a reference library with REMiner-defined and RepeatMasker-defined RE types.
Incorporated analytical options including zoom and RE type selection.
Validated functionality using the human chromosome Y sequence.

Main Results:

REViewer effectively visualizes RE occurrences within RE arrays and genomic regions.
The tool can display up to 6000 REs in interactive line maps.
Query size limitations are dependent on external RE mining tools, not REViewer itself.

Conclusions:

REViewer is an efficient tool for visualizing repetitive elements in complex genomic regions.
The tool enhances the study of RE arrays and their genomic context.
REViewer supports genomic research by providing interactive visualization capabilities.
