Other questions in this quiz

2. Why is the DNA sample cooled from 70 degrees to 55 degrees?

  • Allows primers to attach to DNA strands and mark where DNA polymerase attaches
  • Allows the hydrogen bonds between the two strands of the DNA to break causing them to separate
  • Allows DNA polymerase to add free nucleotides to make a new molecule of DNA
  • To allow reverse transcriptase to convert RNA to DNA

3. What is gene therapy?

  • Removal of functional DNA to be cloned
  • Removal of non functional DNA to prevent further issues
  • Insertion of functional DNA to counteract a non functional gene
  • Insertion of extra chromosomes to counteract non functional genes

4. What is a clone?

  • A group of similar organisms formed from two parents
  • A group of similar organisms formed from a single parent
  • A group of genetically identical organisms formed from a single parent
  • A group of genetically identically organisms formed by sexual reproduction

5. Which of these is NOT used to form recombinant DNA?

  • Reverse transcriptase
  • RNA polymerase
  • Restriction endonucleases
  • DNA polymerase
  • DNA ligase
