A)Yes, the resulting protein will always be different when a mutation occurs B) No, because this is a silent mutation and the amino acids for each codon are the same.
C) No, because even though CCU and CCG code for different amino acids, one amino acid won’t alter the protein
D) Yes, because CCU and CCG do not code for the same amino acid.

According to the rna world hypothesis, rna acted as the genetic material and catalyzed reactions in ancient cells. what conclusion can you draw from this?               a.  this implies that dna and proteins aren't essential in cells today.    b.  this implies that rna can catalyze any chemical reaction that enzymes catalyze.    c.  this implies that if a cell has a problem with its dna, its rna can compensate for the damaged dna.    d.  this implies that dna and proteins evolved after rna.
