friedrich miescher
james watson and francis crick
marshall nirenberg and heinrich matthaei

Explanation:

Rosalind Franklin was a chemist whose X - ray diffraction images of DNA were crucial for understanding its structure but she did not create the model. Friedrich Miescher discovered nucleic acids. Marshall Nirenberg and Heinrich Matthaei made contributions to understanding the genetic code. James Watson and Francis Crick, in 1953, built the first accurate model of DNA (a double - helix model) using data from Franklin and others.

James Watson and Francis Crick
