Introduction to RNA Sequencing

This lecture explains about the RNA sequencing process and the methods or RNA splicing is explained. It also states the use of RNA sequencing in molecular biology. RNA Sequencing, often known as entire Transcriptome Shotgun Sequencing, is a science that uses the capabilities of subsequent-iteration sequencing to disclose a photo of RNA presence and wide variety from a genome at a given second in time.The transcriptome of a cell is dynamic; it consistently alterations. The latest developments of subsequent-generation sequencing allow for improved base insurance policy of a DNA sequence, as well as bigger sample throughput. This enables sequencing of the RNA transcripts in a cell, offering the capability to seem at substitute gene spliced transcripts, post-transcriptional adjustments, gene fusion, mutations/SNPs and alterations in gene expression. In addition to mRNA transcripts, RNA sequencing can appear at extraordinary populations of RNA to comprise complete RNA, small RNA, akin to miRNA, tRNA, and ribosomal profiling. RNA Sequencing can also be used to check exon/ intron boundaries and affirm or amend earlier annotated 5’ and three’ gene boundaries. Ongoing RNA sequencing research includes watching cell pathway differences throughout infection, and gene expression degree alterations in melanoma stories. Previous to NGS, transcriptomics and gene expression reviews had been accomplished with expression microarrays, which incorporate 1000s of DNA sequences or probes that probably healthy complementary sequences in the sample, making available a profile of all transcripts being expressed. This used to be later finished with serial evaluation of gene expression.
