Assignment Dnai

Assignment: using DNAi as a learning tool. (Answer)   1. Phoebus Levene read the structure and function of Nucleic blisterings. Levene distinguish the contrastive forms of nucleic acid, DNA, and RNA. He alike found out that DNA contains adenine, guanine, thymine, cytosine, and deoxyribose and that there is also a phosphate group included. He bursted the comp binglents of DNA: ribose and deoxyribose, with the determination of the component, it is shown that the components were coupled to nameher in the localize phosphate-sugar- root word to form units. These units atomic number 18 called  al-Qaida, which state that DNA molecules consist of stings of nucleotide unit linked together by the phosphate group. This is the backrest bone of the molecule. Levenes lam is the key basis for the constitute that later on determines the structure of DNA. Levene is best known for his work on tetranucleotide possibility which states that DNA is made up of embody amounts of adenine, guanine, thymine, and cytosine. Before, people melodic theme that DNA was organized into restate tetranucleotides in a vogue that could not carry patrimonial information. DNA was seen that the protein component of chromosomes was suasion to be the basis of heredity.  untimely experiments suggested that the four base molecules A, C, G, and T,  pass away in slightly equal ratios. Levene, who had discovered ribose sugar, and went on to discover deoxyribose sugar, suggested the structure of nucleic acid as a repeating tetramer, found on a repeating phosphate - sugar which is the base unit is called a nucleotide. The simplicity of this structure implied that nucleic acids were too equal to contribute to Gordian genetic variation. Attention thereafter focussed on protein as the probable hereditary substance.   2. a) The difference among the 2DNA fiber samples that Rosalind Franklin had access is that one is more highly provide than the other. b) What Rosalind was able to deduce from t! he different fibers and their pattern, is the basic dimensions of DNA...If you want to get a full essay, order it on our website: OrderEssay.net
