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.
DNA has a deoxyribose sugar; RNA has a ribose sugar DNA is a double stranded helix; RNA is a single stranded helix RNA has the nitrogen base uracil instead of thymine (thy â¦ mine is one of the four bases in DNA).here are three main ways in which DNA differs from RNA. First, RNA is single-stranded unlike DNA which is double-stranded. Second, DNA contains deoxyribose while RNA contains â¦ ribose. Third, the base for adenine is thymine in DNA and uracil in RNA.
