Other questions in this quiz

2. What is gene therapy?

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

3. Which of these was NOT an aim of the Human Genome Project?

  • To consider legal and ethical issues
  • To locate genes on the human chromosomes
  • To use genetic information to produce ideal humans
  • To determine all base sequences in DNA and the genes they form

4. What is recombinant DNA?

  • Undifferentiated cells that have the potential to become specialised
  • Foreign DNA inserted into another section of DNA
  • Incorrect DNA
  • DNA that codes for a non functional protein

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

  • Allows DNA polymerase to add free nucleotides to make a new molecule of DNA
  • 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
  • To allow reverse transcriptase to convert RNA to DNA
