Transcription of genes by rna polymerase requires energy, so a bacteria's operon is usually not always turned on. in e. coli bacteria, the trp operon encodes genes for the synthesis of tryptophan, and the lac operon encodes genes for the digestion of lactose. which strain of e. coli is likely to use its energy most efficiently?

Dna has unique properties that allow it to accurately retain genetic information, even after multiple rounds of replication. one aspect of dna that allows it to accurately store genetic information is the base pairing from chargaff\'s first rule of the four nucleotide bases. if the c content of a dna molecule is 22%, what are the percentages of the remaining bases?
