Which of the following statements best describes why the change in only one DNA base of a gene does not always result in a different protein being produced by the gene? The change prevents mRNA from being made.

The change creates an additional mRNA strand.

Some codons are translated from DNA.

Some codons code for the same amino acid.

An enzymatic hydrolysis of fructose-1-p, fructose-1-p(aq) + h2o(l) - fructose (aq) + pi (aq) was allowed to proceed to equilibrium at 25°c. the original concentration of fructose-1-p was 0.2 m, but when the system had reached equilibrium, the concentration of fructose-1-p was only 6.52 x 10^-5 m. calculate the equilibrium constant for this reaction and the free energy of hydrolysis of fructose-1-p.
