Fig. 2From: Long non-coding RNAs in Oral squamous cell carcinoma: biologic function, mechanisms and clinical implicationsThe steroid receptor RNA activator (SRA) lncRNA contains 4 subdomains. The human SRA has a length of 870 nt, organized into 4 sub-domains and 25 helices. Four biochemical techniques (SHAPE, in-line, DMS and RNase V1) were used to obtain the secondary structure. Blue, domain I; green, domain II; black, domain III; yellow, domain IVBack to article page
