Dna and rna, the nucleic acids, are the molecules responsible for the hereditary information that controls the protein synthesis in living organisms the name “nucleic” derives from the fact that they were discovered (by the swiss biochemist friedrich miescher, in 1869) within the cell nucleus. Answer: unicellular organisms may have developed from procaryotes to increase metabolic efficiency (chloroplast and mitochondria), and a nucleus, which contains long strands of dna structured in chromosomes prokaryotic vs eukaryotic organelles in eukaryotic cells cytoskeleton.
