I believe the thyroid controls most, if not all of those things. (Again, I'm not entirely sure.)
DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. The only difference between ribose and deoxyribose is that ribose has one more -OH group than deoxyribose, which has -H attached to the second (2') carbon in the ring. DNA is a double-stranded molecule, while RNA is a single-stranded molecule.
Drosophilia, is the genus name.
