1 Introduction
High-throughput DNA sequencing technologies, including next-generation sequencing and the newly emerging third-generation sequencing, enable the gene sequences of living organisms to be probed in a cost-effective manner (Shendure and Ji, 2008). These sequencing technologies have also been adapted for RNA sequencing (RNA-seq), which enables the expr.
2 RNA Sequencing
RNA-seq uses high-throughput sequencing of nucleic acids to determine the nucleotide sequence of RNA molecules as well as the quantities of specific RNA species within populations of RNA molecules. RNA-seq analysis requires specialized computational tools that can account for the shortcomings of sequencing technologies, including the generation of .
3 Rna-Seq Data Science: from Raw Data to Effective Interpretation
RNA-seq is multifaceted and can be used to uncover and expound new insights on, for example, a dysregulated gene or defective protein that has a downstream effect leading to a disease state (Costa et al., 2010). Computational analysis of RNA-seq data is central to decoding the biological complexities in the transcriptomes of living organisms, inclu.
4 Read Alignment
Read alignment is an essential step in RNA-seq downstream analysis. RNA-seq data typically lack information about the order and origin of the reads, including the specific part, homolog, or strand of the genome from which they originate. Computational alignment of the reads to an annotated reference transcriptome can establish where on the genome t.
5 Quantitative Analysis of Gene Expression
RNA-seq enables quantitative analysis of gene expression at the level of alternative transcripts. The sequence fragments derived from mRNA can reveal which genes are expressed and how strongly they are expressed. Additionally, differential expression (DE) analysis can show how expression levels change under different conditions or between different.
6 Measurement of Allele-Specific Expression
RNA-seq can measure allele-specific expression (ASE or allelic expression) to uncover the cis-regulatory effects of genetic variants (McKenna et al., 2010; Castel et al., 2015; Raghupathy et al., 2018). ASE represents gene expression measured independently for the paternal and maternal alleles of a gene. In a typical RNA-seq experiment, ASE can be .

Circular RNA (circRNA) is a large class of RNA molecules with a covalently closed circular structure that plays important roles in various biological processes and metabolic mechanisms (Wu et al., 2020). In recent years, a variety of computational tools have been developed for circRNA study (Gao and Zhao, 2018; Chen et al., 2021). Identification of.

What is bioinformatics & how does it work?
Bioinformatics, specifically in the context of genomics and molecular pathology, uses computational, mathematical, and statistical tools to collect, organize, and analyze large and complex genetic sequencing data and related biological data.
What is the first step in WGS bioinformatics analysis?
The first step in almost all WGS bioinformatics analyses is quality control of the raw sequencing data. It is important to remove poor-quality sequence data and technical sequences (i.e., adapter sequences). Highly accurate sequences are required for SNP detection, enabling the detection of actual SNPs and distinguishing from sequencing artifacts.
What resources does the NCBI have for Bioinformatics?
The NCBI hosts a multitude of resources for bioinformatics and provides access to over 35 sequence databases including:
GenBank and PubMed. GenBank also coordinates with repositories maintained by European Molecular Biology Laboratory (EMBL) and DNA Data Bank of Japan (DDBJ).
