The initiation of DNA synthesis requires: (A) Five carbon sugar, (B) Deoxyribose alone, (C) A sho RNA molecule, (D) Proteins with free hydroxyl groups
Answer is C. The initiation of DNA synthesis requires priming by a sho length of RNA, about 10 to 200 nucleotides long. In E coli this is catalyzed by dnaG (primase), in eukaryotes, DNA Pol a synthesizes these RNA primers. Harper30e pg: 383
