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 complementaryDNAstrand to form the famous double helix).
The terms sense and antisense were coined by Paul Zamecnik to show the complementary, double-strand nature of DNA. One strand consisted of alternating patterns of the four nucleotides that make up DNA adenine, cytosine, guanine and thymine and it could be read in order.
