miRNA databases (e.g., miRBase)

miRNA databases like miRBase are specialized online repositories that catalog information about microRNAs (miRNAs), which are small RNA molecules involved in regulating gene activity. These databases store details such as miRNA sequences, their biological sources, and experimental data. Researchers use them to identify, compare, and study miRNAs across different species, helping to understand their roles in health and disease. Essentially, they serve as comprehensive reference libraries that facilitate scientific discovery and validate miRNA-related findings.
