(2014) identified a heterozygous c.8357G-A transition (c.8357G-A, NM_004370) in the COL12A1 gene, resulting in a gly2786-to-asp (G2786D) substitution in the triple-helical domain. Abnormality at the protein level was … WebAn RNA triple helix consists of three strands: A Watson-Crick RNA double helix whose major-groove establishes hydrogen bonds with the so-called "third strand". In the past 15 years, it has been recognized that these major-groove RNA triple helices, like single-stranded and double-stranded RNA, also mediate prominent biological roles inside cells.
