In 1935, she produced an original theory of the gene in which she suggested that the specificity of the gene resides in the amino acid sequences of the gene. She made the connection between the linear sequence of the gene and of the amino acids in the polypeptide chain.
During her career, Wrinch investigated the structure of globular protein molecules, including egg albumin and was engaged in a scientific controversy over the structure of globular proteins. She was a prolific writer and produced papers dealing with topics including interpretation of x-rays studies of crystals and proteins, Fourier transformations, mineralogy, and the structure of protein crystals. She died in 1980 in the United States of America.
