What is an RNA Library?

An RNA library is a collection of RNA molecules that have been prepared for sequencing or analysis. It is commonly used in RNA sequencing (RNA-Seq) to study gene expression, transcriptome profiling, and other molecular biology applications.
The process of creating an RNA library typically involves:
RNA Extraction – Isolating RNA from a biological sample.
Fragmentation – Breaking RNA into smaller pieces for sequencing.
Reverse Transcription – Converting RNA into complementary DNA (cDNA).
Library Preparation – Adding adapters and preparing the sample for sequencing.
Sequencing – Using high-throughput sequencing technologies to analyze the RNA content.
RNA libraries are essential for understanding gene expression patterns, identifying novel transcripts, and studying diseases at the molecular level.
