Which of the following most accurately describes the anticodon? A. Contains a sequence complementary to the codon. B. Reintroduces thymine back into the sequence and removes uracil. C. Contains the sequence in the reverse orientation (3-5 vs 5-3). D. Contains a sequence identical to the codon.
What is a nonsense mutation? A change from a codon for one amino acid to a codon for another amino acid. A change in a degenerate codon position that doesn't change the meaning of the codon. A change from an amino acid codon to a stop codon. A change that adds or deletes a base from a codon. A change causing the protein to start in the wrong place.
1. What does it mean when we say the genetic code is redundant? a) A single codon can specify the incorporation of more than one amino acid. b) The genetic code is universal (the same for all organisms). c) The genetic code is different for different organisms. d) More than one codon can specify the incorporation of the same amino acid.
Which statement is correct about amino acids and codons? Group of answer choices One codon specifies different amino acids. Several different codons can specify the same amino acid. Each amino acid is specified by only one codon. Some amino acids have no link to a codon
