Unformatted text preview: ) although there are only 20 amino acids (the building blocks of (2) proteins), the genetic code consists of 64 codons. This makes the codons This genetic code degenerate. degenerate For these reasons, translating the genetic code into protein is For a complex process, requiring several components and the action of two adapter molecules: tRNA and the enzyme two tRNA aminoacyl synthase. aminoacyl BIS101­001, Spring 2013—Genes and Gene Expression, R.L.
