Fig. 2From: Characterization of miRNA profiles in the mammary tissue of dairy cattle in response to heat stressFrequency distribution of detected small RNAs (18–30 nt)based on all reads. The major reads from small RNAs were 20 to 24 nucleotides in length (accounting for 91.14% of total number). Dominant reads of small RNAs were 22 nucleotides in length (41.38%), followed by 21 and 23 nucleotides, and lastly 20 and 24 nucleotidesBack to article page
