What is the answer and why?

8. (four marks) In the course of efforts to decipher the genetic code, an experiment very similar to the following was_performed. Synthetic mRNA with the following sequence was_created. This synthetic mRNA was placed in a test tube containing all the cellular components required for protein synthesis, and indeed protein synthesis occurred. It was not possible to control the point on the mRNA at which translation started. A number of different polypeptides were created, each consisting of a string of identical amino acids, although the amino acids differed between different strings. How many different types of polypeptides would you expect to be produced?_ _ _ _ _ _ - - - - - - -- - - - - - - - --. - - - - - - d. 12 b. e. 2 C
