  1. point mutation
  2. missense mutation
  3. A site
  4. translation
  5. ribozyme
  1. a One of a ribosome's three binding sites for tRNA during translation. Holds the tRNA carrying the next amino acid to be added to the polypeptide chain.
  2. b The synthesis of a polypeptide using the genetic information encoded in an mRNA molecule. There is a change of languagefrom nucleotides to amino acids
  3. c An enzymatic RNA molecule that catalyzes reactions during RNA splicing.
  4. d The most common type of mutation, a base-pair substitution in which the new codon makes sense in that it still codes for an amino acid.
  5. e A change in a gene at a single nucleotide pair

5 Multiple Choice Questions

  1. A specific nucleotide sequence in DNA that binds RNA polymerase and indicates where to start transcribing RNA
  2. opposite ex: anticodon
  3. A complex assembly that interacts with the ends of an RNA intron in splicing RNA, releasing the intron and joining the two adjacent exons.
  4. One of a ribosome's three binding sites for tRNA during translation. Holds the tRNA carrying the growing polypeptide chain. (P stands for peptidyl tRNA
  5. 1) A deficiency in a chromosome resulting from the loss of a fragment through breakage. (2) A mutational loss of one or more nucleotide pairs from a gene.
