H Gene to Protein Vocabulary

Match the following

• Poly A tail

• bonds connecting amino acids together to form polypeptide chain

• polypeptide chain

• A chain of amino acids linked together by peptide bonds

• 5' cap

• modified end of the 3' end of an mRNA molecule consisting of the addition of 50 to 250 adenine nucleotides during RNA processing

• peptide bonds

• 5' end of pre-mRNA molecule modified by the addition of a cap during RNA processing

Match the following

• nonsense mutation

• point mutation that changes a codon to a STOP, resulting in a shorter and usually nonfunctional protein

• missense mutation

• point mutation that results in a codon that codes for a different amino acid, changing the protein structure

• silent mutation

• point mutation that does not change the amino acid sequence or protein
