31. T or F. In pre-mRNA splicing, the 5â splice site, 3â splice site, and the cleavage site in the
intron sequence each have a consensus nucleotide sequence.
32. T or F. The addition of an amino acid to a tRNA molecule is an example of a molecular
switch.
33. T or F. The binding of a ligand to its specific plasma membrane receptor is an example
of a molecular switch.
34. T or F. Energy obtained from ATP hydrolysis is used to attach each amino acid to its
tRNA molecule in a high energy bond that is used later in the ribosome to join an amino
acid into the polypeptide chain.
35. T or F. Every new protein, as it emerges from RNA polymerase in the nucleus, is
comprised of amino acids that have been joined together in a linear chain.
36. T or F. The ribosome has a total of 3 RNA binding sites, including the A, P, and E sites.
