Early researchers expected the genetic material to be protein rather than DNA because amino acids are much simpler than nucleotides, and thus easier to work with. proteins do not exist inside nuclei, and scientists knew that the genetic material was in the nucleus. proteins have more than 20 different monomers, while DNA has only 4; DNA just seemed too simple to carry complex  genetic instructions. they hadn't found any DNA inside nuclei. Question 2    1 / 1 point The complementary strands that make up a DNA molecule are said to be antiparallel because DNA replication requires an RNA primer. weak hydrogen bonds hold the 2 strands together, while strong covalent bonds bind one nucleotide to the next in the  backbone of the molecule. each strand is oriented with the nucleotides running in the opposite direction.
