double stranded helix

基本解释

If a solution of DNA in dilute buffer is heated, the DNA double-stranded helix melts to single strands over a narrow temperature range.
如果一个缓冲液稀释的DNA被加热，在DNA双链螺旋单丝融化了一个较窄的温度范围。
When the new owners came in, they worked in their laboratories and created versions of humans with a different DNA-the two-stranded, double-helix DNA.
当新业主前来，他们在实验室工作，并创造了不同版本的具有双螺旋DNA的人类。

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分子那样形成双链螺旋，通过沃森-克里克配对，两个螺旋的核苷链互补。

DNA. This molecule is a double-stranded helix made from four different types of sub-molecule.
ECONOMIST: Genetics gets more complicated
To Dr Baselt this suggested that tiny magnetic particles might be attached to molecules using either antibodies (which will bond to proteins, sugars and so on) or single-stranded DNA (which will bond to a complementary DNA strand to form the famous double helix).
