• Homework Questions from Professor Jacobson
    • Nature’s machinery for copying DNA is called polymerase. What is the error rate of polymerase? How does this compare to the length of the human genome, and how does biology deal with that discrepancy?
    • How many different ways are there to code (DNA nucleotide code) for an average human protein? In practice, why don’t all of these codes work for the protein of interest?
  • Homework Questions from Dr. LeProust
    • What’s the most commonly used method for oligo synthesis currently?
    • Why is it difficult to make oligos longer than 200 nt via direct synthesis?
    • Why can’t you make a 2000 bp gene via direct oligo synthesis?
  • Homework Questions from George Church
    • [Using Google & Prof. Church’s slide #4] What are the 10 essential amino acids in all animals, and how does this affect your view of the “Lysine Contingency”?
    • [Given slides #2 & #4 (AA:NA and NA:NA codes)] What code would you suggest for AA:AA interactions?
