complementary dna strands
常見例句
- RNA molecules form double stranded helices, just as do DNA molecules, by Watson Crick pairing of nucleotides on the two complementary strands of the helix.
RNA分子能像DNA分子那樣形成雙鏈螺旋，通過沃森-克里克配對，兩個螺旋的核苷鏈互補。 - Now DNA is a double helix and I've only shown you one part of the helix, right? I've shown you one upright strut and a base hanging off of it, but it forms a double helix because complementary strands of DNA strongly associate with one another and that's a very stable structure.
NA是雙螺旋,我只是給你們講了螺旋的一邊,我給你們演示,一條鏈的支柱及堿基團,但其能構(gòu)成雙螺旋,是因為DNA是完全互補的兩條鏈,彼此之間結(jié)合緊密,結(jié)構(gòu)異常穩(wěn)定
