Understanding the Role of tRNA

Transfer RNA (tRNA) is crucial to various biological processes, including cellular survival, proliferation, differentiation, and metabolic activities. It plays a significant role in cell signaling and responses to stress, as well as in the life cycle of viruses such as HIV-1. High-throughput RNA sequencing has unveiled the intricate roles of small RNAs, enhancing our comprehension of their importance across diverse biological contexts. However, challenges such as post-transcriptional modifications and stable secondary structures of tRNA have historically hindered efficient sequencing methods.
