5 Matching questions

  1. signal-recognition particle (SRP)
  2. trans-
  3. TATA box
  4. ribozyme
  5. terminator
  1. a An enzymatic RNA molecule that catalyzes reactions during RNA splicing.
  2. b across ex:transcription
  3. c A protein-RNA complex that recognizes a signal peptide as it emerges from the ribosome.
  4. d A promoter DNA sequence crucial in forming the transcription initiation complex.
  5. e In prokaryotes, a special sequence of nucleotides in DNA that marks the end of a gene. It signals RNA polymerase to release the newly made RNA molecule, which then departs from the gene.

5 Multiple choice questions

  1. 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.
  2. A region of a DNA molecule that is transcribed into an RNA molecule.
  3. An RNA molecule that functions as an interpreter between nucleic acid and protein language by picking up specific amino acids and recognizing the appropriate codons in the mRNA.
  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. The DNA strand that provides the template for ordering the sequence of nucleotides in an RNA transcript.

5 True/False questions

  1. promoterA specific nucleotide sequence in DNA that binds RNA polymerase and indicates where to start transcribing RNA

          

  2. -scriptA three-nucleotide sequence of DNA or mRNA that specifies a particular amino acid or termination signal; the basic unit of the genetic code.

          

  3. frameshift mutationA change in a gene at a single nucleotide pair

          

  4. messenger RNA (mRNA)An RNA molecule that functions as an interpreter between nucleic acid and protein language by picking up specific amino acids and recognizing the appropriate codons in the mRNA.

          

  5. mutagenA rare change in the DNA of a gene, ultimately creating genetic diversity.
