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.
RNA is single stranded,rna has uracil instead of thymine, rna has ribose sugar while dna has deoxyribose,rna is found everywhere in the cell and dna is only in the nucleus. Name three differences between dna & rna. helicase-the enzyme-unzips the two strands of a dna molecule at the hydrogen bonds between the paired nitrogen bases. what is the first step of dna replication and what enzyme is involved in this step.
