Molecular Sewing Machines........
a: Dna ligase ~
b: a sewing machine
What: DNA ligase is an enzyme. Enzymes, biological catalysts, generally perform 2 functions. They provide an ideal spatial orientation for 2 or more molecules to react. Once said molecules are aligned correctly, the enzyme reversibly interacts with the molecules to lower the transition energy for that particular reaction.
So, a valid association for DNA ligase is a sewing machine. A sewing machine can do 2 things; it can provide a surface for cloth to be aligned correctly, and it provides the means for the 2 separate piece of cloth to bound. The means of connection is the needle and the thread. A sewing machine is not changed by this process. It can perform the same task many many times.
