Gerard Robert Wyatt (3 September 1925, in Palo Alto, California – 28 March 2019, in Kingston, Ontario)[1] was an American-Canadian biochemist and entomologist, specializing in insect physiology.
[2] He attended Victoria College but transferred to the University of British Columbia, where he graduated in 1945 with a bachelor's degree in zoology.
He then worked for a year at the UC Berkeley laboratory of Edward Steinhaus, an expert on insect-transmitted pathogens.
[5][1] During the late 1940s and early 1950s Gerard Wyatt studied the ratios of the four DNA bases - adenine, guanine, thymine and cytosine - in eukaryotic cells.
However, Wyatt was thought by some to use better techniques; he also confirmed the presence of 5-methylcytosine in the DNAs of some organisms, which revised the ratios in those species to bring them nearer to 1.
For the past two years this DNA was said to have the strange property of lacking cytosine, a feature obviously impossible for our model.
