Coverage of genome by assembly: for this metric, BGI's assembly via SOAPdenovo performed best, with 98.8% of the total genome being covered. All assemblers performed relatively well in this category, with all but three groups having coverage of 90% and higher, and the lowest total coverage being 78.5% (Dept. of Comp. Sci., University of Chicago ...
RNA-Seq [1] [2] [3] is a technique [4] that allows transcriptome studies (see also Transcriptomics technologies) based on next-generation sequencing technologies. This technique is largely dependent on bioinformatics tools developed to support the different steps of the process.
However, transcriptomes are cheaper to sequence than complete genomes and may be obtained without the use of a pre-existing reference genome. [ 1 ] It is not uncommon to translate RNA sequence into protein sequence when using transcriptomic data, especially when analyzing highly diverged taxa.
Prior to the development of transcriptome assembly computer programs, transcriptome data were analyzed primarily by mapping on to a reference genome. Though genome alignment is a robust way of characterizing transcript sequences, this method is disadvantaged by its inability to account for incidents of structural alterations of mRNA transcripts ...
The term transcriptome is a portmanteau of the words transcript and genome; it is associated with the process of transcript production during the biological process of transcription. The early stages of transcriptome annotations began with cDNA libraries published in the 1980s. Subsequently, the advent of high-throughput technology led to ...
In bioinformatics, sequence assembly refers to aligning and merging fragments from a longer DNA sequence in order to reconstruct the original sequence. [1] This is needed as DNA sequencing technology might not be able to 'read' whole genomes in one go, but rather reads small pieces of between 20 and 30,000 bases, depending on the technology used. [1]
Transcriptome analysis is the study of all the RNA transcripts that are produced by the genome of an organism. Linked-read sequencing has been used by researchers to assemble transcript isoforms and alternative splicing events. [ 12 ]
G&T-seq (short for single cell genome and transcriptome sequencing) is a novel form of single cell sequencing technique allowing one to simultaneously obtain both transcriptomic and genomic data from single cells, allowing for direct comparison of gene expression data to its corresponding genomic data in the same cell...
