Final answer:
The claim that a stop signal like '*' should be included in the protein sequence is false. Protein synthesis is terminated by stop codons (UGA, UAA, UAG) that signal the end of translation, not by a specific amino acid or stop signal within the protein sequence itself.The right answer is False
Step-by-step explanation:
The statement that the stop signal, *, should be included as part of the protein sequence to indicate the end of the protein is false. Proteins are synthesized by linking amino acids together in a chain during a process called translation. This process continues until the ribosome encounters one of three stop codons: UGA, UAA, or UAG. Unlike amino acids which each have a corresponding tRNA and codon, stop codons do not code for an amino acid but instead signal the termination of translation by the recruitment of a release factor. Thus, they signal the end of the amino acid sequence of a protein but are not part of the protein itself. After translation, the new protein may undergo post-translational modifications, including the removal of any signal sequences that directed the protein to its specific cellular compartment during protein targeting, but the stop codon itself is not translated into a signal or part of the protein.
