WebHowever in biological systems, it is very rare that RNA is ever made with its complementary strand. mRNA is single stranded and linear, but it is never transcribed with its complementary strand, rRNA, tRNA, siRNA, miRNA, and the plethora of other RNA biomolecules are either linear or self complementary and bound to itself. WebUnlike double-stranded DNA, RNA is usually a single-stranded molecule (ssRNA) [1] in many of its biological roles and consists of much shorter chains of nucleotides. [2] However, double-stranded RNA (dsRNA) can form and (moreover) a single RNA molecule can, by complementary base pairing, form intrastrand double helixes, as in tRNA.
