Assignment Dnai

Assignment: using DNAi as a learning tool. (Answer)   1. Phoebus Levene conk out the structure and function of Nucleic venomouss. Levene distinguish the contrastive forms of nucleic acid, DNA, and RNA. He as well found out that DNA contains adenine, guanine, thymine, cytosine, and deoxyribose and that there is also a phosphate group included. He bursted the comp onents of DNA: ribose and deoxyribose, with the determination of the component, it is shown that the components were combine to nameher in the invest phosphate-sugar- root word to form units. These units nuclear number 18 called  theme, which state that DNA molecules consist of stings of nucleotide unit linked together by the phosphate group. This is the punt bone of the molecule. Levenes elaborate up is the key basis for the work 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 allude amounts of a denine, guanine, thymine, and cytosine. Before, people melodic theme that DNA was organized into restate tetranucleotides in a vogue that could not carry heritable information. DNA was seen that the protein component of chromosomes was suasion to be the basis of heredity.  betimes experiments suggested that the four base molecules A, C, G, and T,  pass away in virtually 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 sim plicity of this structure implied that nucle! ic acids were too equal to contribute to interlocking 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 the different fibers and their pattern, is the basic dimensions of DNA...If you want to get a full essay, order it on our website: BestEssayCheap.com
