The correct statement about RNA polymerase and DNA polymerase is (1 point) A: Synthesis of polynucleotide chain using nucleoside diphosphate B: RNA polymerase requires primers and bases are added at the 5′-end of the extended polynucleotide chain C: DNA polymerase can only synthesize DNA using RNA as a template D: DNA polymerase can add nucleotides on both ends of a chain at the same time E: , DNA polymerase and RNA polymerase can catalyze the formation of 3',5'-phosphodiester bond

In 1953, Watson and Crick found that: A: Two polynucleotide chains form double helix structure of DNA by hydrogen bond linkage B: DNA replication is semi-conservative and usually form heteroduplex DNA consisted of one parental chain and one daughter chain C: Three continuous nucleic acids consist of a genetic code D: Genetic material is usually DNA instead of RNA
