The structure of the nucleic acids DNA and RNA.

A)Briefly describe the complex body part of the nucleic acids deoxyribonucleic acid and RNA. (6) B)How do their deflections in structure suit the different roles in which they revivify in quick cells. (10) C)What is meant by the term the genetic code (4) a) DNA be much the equal in a twist of aspects. Both argon create up of large polymer bondage of nucleotides. DNA is much longitudinal than RNA (DNA-1 billion ground pairs and RNA - 10,00 bases) solely are both long ropey macromolecules. This basic diagram of a nucleotide is correct for both DNA and RNA, the only difference is that the pentose sugar in the decoct is deoxyribose for DNA and ribose for RNA. The nucleotides are binded unitedly among the phosphate of 1 and the sugar of the next. The bond utilize is a strong diester linkage. The strands are sequences of these nitrogen-containing bases. There are 4 different types of bases, adenine (a), one thousand (g), thymine (g) and cytosine (c) but in RNA thymine is replaced with uracil (u). Each base is complementary to an other and so DNA is made up of complementary base pairs. amp and Guanine are Purine whereas thyroxin and Cytosine are Pyrimidines. Purines timber 2 ring strucutres and pyrimidines have only one ring.

Because of this purines nominate only bind to pyrimidines and offense versa thus setting up the links for A-T and G-C. In DNA, in that respect are two strands of nucleotides. They are complementary and antiparallel. This means that the codes are opposite and so bind to each other and live on in opposite ways. An example would be where one locating runs ATCG, the other would run CHAT and so they would bond unneurotic between the bases with a h! ydrogen bond. RNA is mostly oneness desert except for in some viruses. The code... If you want to annoy a full essay, order it on our website: OrderEssay.net
