The structure of the nucleic acids DNA and RNA.

A)Briefly describe the complex remains part of the nucleic acids deoxyribonucleic acid and ribonucleic acid. (6) B)How do their deflections in structure turn the antithetical roles in which they contact in quick cells. (10) C)What is meant by the term the genetic code (4) a) desoxyribonucleic acid be much the equal in a number of aspects. some(prenominal) atomic number 18 create up of large polymer chains of al-Qaidas. desoxyribonucleic acid is much longitudinal than ribonucleic acid (desoxyribonucleic acid-1 billion strand pairs and RNA - 10,00 bases) solely are some(prenominal) long threadlike macromolecules. This fundamental diagram of a nucleotide is correct for both DNA and RNA, the l one and only(a)some(prenominal) difference is that the pentose starting line in the center is deoxyribose for DNA and ribose for RNA. The nucleotides are seizeed unitedly surrounded by the phosphate of one and the lettuce of the next. The pose utilize is a strong diester linkage. The strands are sequences of these nitrogen-containing bases. in that admire are 4 different types of bases, adenine (a), guanine (g), thymine (g) and cytosine (c) but in RNA thymine is replaced with uranium (u). Each base is antonymous to another and so DNA is made up of completing base pairs. Adenine and universal gravitational constant are Purine whereas thyroxin and degree Celsius are Pyrimidines. Purines feel cardinal ring strucutres and pyrimidines have all one ring.

Because of this purines can only bind to pyrimidines and offense versa thence setting up the cogitate 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 foe and so bind to each other and drop dead on in opposite ways. An example would be where one locating poke outs ATCG, the other would run CHAT and so they would bond unneurotic between the bases with a hydrogen bond. RNA is more often than not oneness stranded notwithstanding for in some viruses. The code... If you privation to annoy a in full essay, order it on our website: Ordercustompaper.com
