, 11) Until the mid-1940s, many scientists considered proteins to be the likely candidates for
ju ju ju ju ju ju ju ju ju ju ju ju



thegenetic material. Why?
ju ju ju ju



Answer: Proteins are the most abundant, universally distributed components in cells. ju ju ju ju ju ju ju ju ju



Becauseof their great structural and functional diversity, they were considered likely

candidates.
