- What observations are consistent with the conclusion that DNA serves as the genetic material in eukaryotes? Select the four correct statements. a. DNA content and ploidy in various cell types( sperm and somatic cells) are related b. DNA is found to be the only macromolecule in eukaryotes that has different subunits. c. Gene transfer is a direct evidence as it has been facilitated by recombinant DNA techniques. d. The correlation of the action and absorption spectra of ultraviolet light support the interpretation that DNA is a genetic material. e.
