They have large appetites, so unless you planted enough for yourself and the butterflies, it can be a depressing sight to see your food crop munched down to its stems by an army of hungry caterpillars.

1 DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. 2  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.
The main difference between DNA and RNA is the sugar present in the molecules. While the. sugar present in a RNA molecule is ribose, the sugar present in a molecule of DNA is. deoxyribose. Deoxyribose is the same as ribose, except that the former has one more OH.
