A new bаcteriа hаs been discоvered оn a rоck from outer space.  This bacteria's DNA contains three different nucleotides:  A, B, and C.  It is discovered that four nucleotides encode each amino acid in the bacteria's proteins.  And, the codons overlap by 2 nucleotides.  Given this information, answer the following fill in the blank questions.  Type a number in the blank.  For example "1". Use the hypothetical sequence to help you out: ACBBCCABACBABC... a. How many different amino acids can be encoded? [1] b. If a single nucleotide is changed, how many amino acids in the encoded protein would likely be affected? [2] c. How many different reading frames are there? [3]
