1. The moon Titan orbits Saturn and is known to have a dense atmosphere and large pools of liquid methane rather than liquid water. Imagine that we evolved there instead of on Earth, and assume a DNA-like molecule is responsible for carrying genetic information in this scenario. Propose changes to the structure of DNA that would make it more likely to evolve in such a place. Draw the structure of your new genetic material, explaining its properties.
