Classification of noncoding RNAs (ncRNAs). Noncoding RNAs are classified into small ncRNAs (< 200 nucleotides) or long ncRNAs (> 200 nucleotides) based on their length. Small ncRNAs are further classified into functional and regulatory noncoding RNAs while long ncRNAs are classified based on their structure, function and location
