The concentrations of a reaction are measured to determine reaction rates. if the concentration of the reaction's product increases from 0.0250m to 0.484m in 3.00mins, determine the average reaction rate during this time period?
1.28 × 10-3 mol/(l × s)
2.55 × 10-3 mol/(l × s)
5.10 × 10-3 mol/(l × s)
1.02 × 10-2 mol/(l × s)

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?
