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.
DNA stands for deoxyribonucleic acid, while RNA is ribonucleic acid. Although DNA and RNA both carry genetic information, there are quite a few differences between them. This is a comparison of the differences between DNA versus RNA, including a quick summary and a detailed table of the differences.
Other than these differences, DNA and RNA are the same. Their phosphates, sugars, and bases show the same bonding patterns to form nucleotides and their nucleotides bind to form nucleic acids in the same way. 1  RNA is a single-stranded nucleic acid.2  RNA has a ribose sugar instead of a deoxyribose sugar like DNA. 3  RNA nucleotides have a uracil base instead of thymine.igure %: Common Secondary Structures of RNA. The main difference between the three-dimensional structures of DNA and RNA is that in RNA the three-dimensional structure is single-stranded. The base-pairing that occurs in RNA is all through regions of self-complementarity.
