During the Translation of MRNA Molecules, the New Polypeptides Are

Multiple Choice

During the translation of mRNA molecules, the new polypeptides are often directed to specific parts of the cell by the presence or absence of short sequences of amino acids called signal peptides. Which of the following would you expect to find in the polypeptides that will eventually fold to become the cytoskeletal proteins tubulin and actin, which are found in the cytoplasm?

A) no signal peptide
B) an amino terminal signal peptide
C) an internal signal peptide
D) a signal anchor peptide
