The resulting channel enabled them to move both single - and double-stranded DNA through the membrane.

所产生的通道使得它们能够通过细胞膜移动单链和双链dna。

Each codon is a specific sequence of three nucleotides (three nucleotide pairs in double-stranded DNA), and each codon codes for a single amino acid unit in a protein.

每个密码子是特异的三核苷酸序列（双链DNA状况下为三个三核苷酸对），每个密码子编码蛋白质的一个氨基酸单位。

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).
