Question
Identify the reasons proteins were generally favored over DNA as the genetic material before 1940. Select all that apply. Proteins were discovered to be present mainly in nucleus of cells, thereby they were almost only present where genetic functions were performed. Abundant knowledge of the structural and enzymatic properties of proteins generated a bias that worked to favor proteins as the hereditary substance. Proteins are composed of 20 different subunits, thereby providing ample structural and functional variation for the multiple tasks that must be accomplished by the genetic material. DNA was discovered in 1940.Explanation / Answer
Q7. c. Proteins are composed of 20 different subunits, thereby providing ample structural and functional variation for the multiple tasks that must be accomplished by genetic material.
Explanation:
The chemical and structural properties of nucleic acids were perceived to be too simple to account for the multitude of inherited traits. Scientists thought that the protein was the genetic material because; proteins were macromolecules with great heterogeneity and functional specificity. Not much was know about the nucleic acids.
