The genetic code is always read
a. 3 bases at a time in the same direction.
b. 4 bases at a time in the same direction.
c. 3 bases at a time and the direction varies.
d. 4 bases at a time and the direction varies.
Extra info: 3 bases being read together is called the triplet code. It is read in one direction to prevent mistranscription from occurring so that the correct protein can be translated and synthesised.
