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 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. 2  DNA is a double stranded molecule while RNA is a single stranded molecule. 3  DNA is stable under alkaline conditions while RNA is not stable.
1. RNA is usually single stranded while DNA is usually double stranded... 2. RNA nucleotides contain ribose as their sugar and DNA contains deoxyribose (a type of ribose without one oxygen molecule) 3. RNA uses the base Uracil which binds to Adenine while DNA uses Thymine as a base that binds to Adenine.. RNA contains the nitrgoenous base uracil instead of the nitrgoenous base thymine found in DNA. 3. RNA is usually single stranded unlike DNA which is a double helix.
