Guanine
What does messenger RNA do?
It carries the RNA that is copied from DNA to ribosomal sites in the cytoplasm.
Proteins that can change the rates of specific reactions.
Enzymes
A natural, nonrenewable fuel such as coal, oil, or gas formed over a very long time in the past from the fossils of living organisms.

How is DNA shaped?
In a double helix

Solar Power
Is renewable energy cheap or expensive? If so, which type is the cheapest?
Yes, it is. Solar energy is the cheapest with its energy coming from the sun.
