Poly(A) tail sequencing is a specialized transcriptomics approach that analyzes the length and composition of poly(A) tails attached to messenger RNAs (mRNAs). The poly(A) tail plays a crucial role in regulating mRNA stability, translation efficiency, RNA localization, and transcript degradation.

By profiling poly(A) tails at transcriptome scale, researchers can better understand RNA processing, alternative polyadenylation, and dynamic changes in gene expression under different biological conditions.
