Assignment1 - Essay Example Its major function is to carry the genetic information to the cytoplasm for the protein synthesis process. However, DNA is present in the nucleus mainly to store the genetic information. DNA is short lived and double stranded while mRND is single stranded and has a short lifespan. A DNA chemical test can be carried out to observe their performance in genetic synthesis. c. Starch and cellulose are polymers having very similar characteristics. They have similar glucose based repeat units and are made up of the same monomer. However, all the repeated units in starch are oriented in one direction while in cellulose; every successive unit of glucose is rotated 180 degrees of around the axis of the backbone chain of the polymer. In experiments, starch is soluble in warm water while cellulose is tough and can only be broken down into simpler units when treated with acids at high temperatures. Starch is therefore used as a major source of energy in human food while cellulose is used in making fibre materials (Markussen et al., 2002). d. Amylose is a D-glucose unit polysaccharide that forms 20-30% of the total starch structure while Amylopectin forms the remaining percentage of the cell starch structure. In experiments, the amylase components do not dissolve in water while Amylopectin dissolves in water. Structurally, Amylose can appear in a pair of distinct helical forms or in a distorted amorphous confirmation. Amylopectin , however, has a non-random branching determined by enzymes and glucose residues (Markussen et al., 2002). e. Myoglobin is a monomer that binds oxygen more tightly than hemoglobin as reflected when oxygen is in the bloodstream is observed to move from hemoglobin to myoglobin. On the other hand, hemoglobin is a tetramer made up of a pair of related subunits of alpha and beta. Their functional difference can be observed in an oxygen uptake experiment under similar conditions for oxygen

Political science - Essay Example ilarly, this paper will also explain the similarities and differences in their own justification for disobedience, and in the manner in which each perceives disobedience to be necessary or beneficial in the circumstances. Sophocles’ Antigone argues that the unwritten and natural law supersedes any form of human law (â€Å"Sophocles Antigone 442 BC†, 2005), which means that the only source or basis of legitimate law is the unwritten and natural law; Antigone believes that duties to the gods are more essential than obedience of the state and law. She argues that she does not fear condemnation from men, but punishment from the gods by failing to honour her obligations to them, which oblige her to bury the dead and not to insult the gods by denying the dead a proper burial. Like Sophocles’ Antigone, Plato’s Socrates believes in a higher standard as the ultimate source of legitimate law, which is the gods. After he had been found guilty of poisoning the minds of young ones, Socrates declared without modesty that his teachings were the gods’ bidding, and that the city of Athens had thrived because of his service to the gods (DAmato, 1976). However, unlike Sophoclesâ€℠¢ Antigone who exclusively believes in one base of legitimate law, Plato’s Socrates also believes that the Athenian judicial system, a tribunal that dispensed justice according to the laws, was also a legitimate basis of law that should be respected; however, Socrates argues that his teachings had made Athens a better state. Sophocles’ Antigone argues that human laws undermine the unwritten and natural law especially because they do not honour the gods and family morals. Antigone gives honour and a principled responsibility to the gods and family equal weight in her defence since she does not want to offend the gods and to attract severe penalties from them (â€Å"Sophocles Antigone 442 BC†, 2005). Like Sophocles’ Antigone, Plato’s Socrates believes that in as much as the Athenian judicial
