- Bioinformatics
Background:
- RNA structure analysis is crucial for understanding gene regulation and function.
- Existing methods for transcriptome-wide RNA structure probing are limited.
- High-throughput sequencing technologies offer new possibilities for RNA analysis.
Purpose of the Study:
- To introduce FragSeq, a novel experimental assay for transcriptome-wide RNA structure probing.
- To provide a practical guide for designing and performing FragSeq experiments.
- To present data analysis tools for quantitative determination of nuclease accessibility.
Main Methods:
- FragSeq combines nuclease digestion with high-throughput cDNA sequencing (RNA-Seq).
- The assay allows simultaneous probing of many distinct transcripts in a single mixture.
- Quantitative analysis determines nuclease accessibility at single-base resolution.
Main Results:

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.

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
