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

Explanation:

• Rosalind Franklin's X - ray diffraction images were crucial for understanding DNA structure but she did not create the model.
• Friedrich Miescher discovered DNA (nuclein) but not its model.
• James Watson and Francis Crick, in 1953, built the first accurate double - helix model of DNA using data from Franklin and others.
• Marshall Nirenberg and Heinrich Matthaei worked on the genetic code (translation of mRNA to proteins) not the DNA model.

Answer:

James Watson and Francis Crick.
