Question 6
 A codon is defined as a
   1.  triplet of bases which codes for a single amino acid
2.  type of protein which affects the production of other proteins
3.  molecule which lines up with the bases on an mRNA molecule
4.  structure which assists in the production of proteins
 

Question 7
 Which of these statements about the mRNA code is false?
   1.  there is a special sequence of bases which codes for the end of translation of the code into a protein molecule
2.  amino acids are coded for through sequences of three bases
3.  most amino acids are coded for by only one sequence of bases
4.  a great deal of experimentation was necessary to crack the mRNA code
