Final answer:
Yes, each signal sequence does specify a particular destination within the cell, directing proteins to where they are needed and then being removed upon arrival.
Step-by-step explanation:
The statement that 'Each signal sequence specifies a particular destination in the cell' is true. Signal sequences at the amino end or the carboxyl end of a protein serve as a sort of 'train ticket,' directing the protein to its intended destination within the cell. For instance, signal sequences guide proteins to the mitochondria, chloroplasts, or other specific compartments. Once the protein arrives at its destination, this sequence is typically removed.
