Answer:

In 1953, Watson and Crick determined the double-helix composition of DNA, that is, the molecule comprising human genes. They found that the composition of DNA was a spiral of two strands of DNA or a double-helix polymer, each comprising a lengthened monomer chain, that is, the nucleotides wrapped around each other.
