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. Planting a separate crop of fennel (or any related member) can help preserve the butterflies in your garden.I especially like Florence fennel, or finocchio, a bulbing variety that gives you a vegetable, an herb, and two spices over its lifespan.n the back of my garden, I have a small patch of fennel (Foeniculum vulgare) that grows year-round and stands five feet tall.
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.
Tweet. The difference between DNA and RNA in the most basic way is that DNA is double stranded whereas RNA is single stranded. The next difference is that DNA is made from deoxyribose and RNA is made from ribose.Ribose has a hydroxyl group attached to it, making it less stable.The third difference is in the complementary nucleotides that DNA and RNA encode for. DNA has thymine (T), guanine (G), adenine (A) and cytosine (C).weet. The difference between DNA and RNA in the most basic way is that DNA is double stranded whereas RNA is single stranded.
