>> If an error is detected - a mismatch (e.g. a G paired with a T) - a trio of proteins (MutL, MutS, MutH) spring into action. One additional thing should be covered in biology teaching -- Not just the process that magically "happens", but how it ends up happening. The said proteins have no free will to just spring into action. I recall being taught during high school about mitosis and meiosis, how this spindle apparatus forms, DNA strands split, etc. How do I connect what happens to the laws of Physics? I understand that I still cannot explain gravity, or why a ball falls to the floor, but biology teaching seems to leave a lot more out, and without saying so.
