Assuming that protein synthesis was under way when the radioactive amino acids were added, which of the following best describes how the radioactivity was distributed in one of the first molecules of Protein X that was completely translated?A.Radioactive amino acids were randomly located throughout the molecule.B.Radioactive amino acids were located only at one end of the molecule.C.Radioactive amino acids were located at both ends, but not in the middle, of the molecule.D.Radioactive amino acids were located in the middle, but not at either end, of the molecule.Answer: B Since protein synthesis was already underway, the N terminal and probs the middle are already completed, so all the radioactive AAs will be at the one end.

The radioactivity distributed in one of the first molecules of Protein X that was completely translated Option B that is : Radioactive amino acids were located only at one end of the molecule

What are radio active amino acids ?

Aspartic acid, alanine, and lower quantities of 3- and 4-carbon amino acids were the radioactive amino acids that were found. This result, along with the complete lack of radioactive glutamic acid, supports the CO-sub 2 reduction mechanism that laboratory members had previously proposed.

Polyatomic molecules make up amino acids. The amino acid will be radioactive if one or more of these atoms are.

Prior to the insertion of radioactive amino acids, the majority of the N-terminal end and likely the middle portion of the protein were already produced because translation had already begun.
