Week 1 HW: Principles and Practices
- Biological engineering application I propose a “DNA Compiler,” a software tool that helps researchers turn DNA designs into safe, synthesis-ready sequences. The main idea is to build safety checks directly into the design process rather than relying only on downstream screening or manual review. The compiler would analyze a DNA sequence, flag potential issues, and suggest safer alternatives (for example, adjusting sequence features or highlighting areas that require review). It would also generate a clear record of how the design was modified or approved. The goal is to make good safety practices automatic and easy to follow.
Homework Questions from Professor Jacobson Nature’s machinery for copying DNA is DNA polymerase. According to the lecture slides, an error-correcting polymerase has an error rate of approximately 1 error per 10⁶ bases added. The human genome is about 3.2 × 10⁹ base pairs long. Comparing these numbers, if replication relied only on polymerase accuracy, we would expect on the order of thousands of errors during replication of a single human genome. This highlights a discrepancy between the intrinsic error rate of polymerase and the need to faithfully copy very large genomes.
