Example 1 · difficulty 1/5
In the nomenclature of the restriction endonuclease EcoRI, the letter 'R' denotes the:
- A. genus of the bacterium from which the enzyme was isolated
- B. species of the bacterium from which the enzyme was isolated
- C. strain of the bacterium from which the enzyme was isolated
- D. order in which the enzyme was isolated
Example 2 · difficulty 2/5
The single-stranded overhangs ('sticky ends') generated when DNA is cut with EcoRI are useful in recombinant DNA technology mainly because they:
- A. pair by complementary hydrogen bonding with matching overhangs, making it easy for DNA ligase to seal the sugar-phosphate backbone
- B. prevent self-ligation of the vector unless a foreign insert is present
- C. allow DNA fragments to enter host cells directly without any treatment of the cells
- D. protect the cut DNA ends from digestion by exonucleases
Example 3 · difficulty 1/5
In a polymerase chain reaction cycle, the step performed at approximately 72 °C, during which Taq DNA polymerase synthesises new DNA strands complementary to the template, is known as:
- A. Denaturation
- B. Primer extension
- C. Annealing
