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。

These are synthetic single-stranded DNA sequences that are, among other things, capable of cutting nearby DNA strands in specific places.

ECONOMIST: DNA computing

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).

The HIV retrovirus, in particular, is a single-stranded RNA virus that duplicates itself in a host cell by converting its genetic code into double-stranded DNA that is then inserted into the host cell.
