8) Early in the twentieth century, Walter Sutton and Theodore Boveri noted that the behavior of
n5 n5 n5 n5 n5 n5 n5 n5 n5 n5 n5 n5 n5 n5




chromosomes during meiosis is identical to the behavior of genes during gamete formation.
n5 n5 n5 n5 n5 n5 n5 n5 n5 n5 n5 n5 n5

11) Until the mid-1940s, manyscientists considered proteins to be the likelycandidates for
n5 n5 n5 n5 n5 n5 n5 n5 n5 n5 n5 n5




the genetic material. Why?
n5 ju n5 n5




Answer: Proteins are the most abundant, universally distributed components in cells. n5 n5 n5 n5 n5 n5 n5 n5 n5




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

candidates.
