Question: Papers published in Nature by Doolittle and Sapienza (1980) and Orgel and Crick (1980) hypothesize that genome size is a balance between which two types of processes? Correct Answer(s) larger genomes requiring larger cell nuclei and thus larger cells Press Space to open selection for replication speed, small genome size, and energetic efficiency that favors reduction in genome size Press Space to open changes in genome size being favored because of their structural effects on cell physiology Press Space to open proliferation of self-replicating genetic units
