PPT-DNA STRUCTURE

DNA is composed of polynucleotide chains The helical structure of DNA Formation of Nucleotides Structure of polynucleotide polymer Each base has its preferred tautomeric form Purine and . 3.3.1: Outline DNA nucleotide structure in terms of sugar (deoxyribose), base. and phosphate.. 3.3.2: State the names of the four bases in DNA.. 3.3.3: Outline how DNA nucleotides are linked together by covalent bonds. DNA Structure. The discovery of the structure. Francis Crick and James Watson. The deoxyribonucleic acid (DNA) molecule is the genetic blueprint for each cell and ultimately the blueprint that determines every characteristic of a living organism. The DNA molecule was discovered in 1951 by Francis Crick, James Watson, and Maurice Wilkins using X-ray diffraction. . Stryer. Short course. Chapter 33. Nucleic Acid Structure. Nucleobase. Nucleoside. Nucleotide. Nucleic acid. Chromatin. Chromosome. Polymeric Structure. Polymer ideal for informational molecule. Ribose and deoxyribose. Nucleic Acids. What do we know already?. i. . The nucleic acids DNA and RNA are polymers of nucleotides. Nucleotides consist of 3 parts. A 5-carbon sugar – ribose or deoxyribose. A phosphate group (acidic & negatively-charged). Essential idea: The structure of DNA allows efficient storage of genetic information.. There is 2m of DNA in each human cell, however the most cells in the human body have a diameter of 10 . μm. . This DNA is divided in chromosomes and coiled around proteins called histones so that it can be efficiently stored in each cell's nucleus. The human genome project which has decoded the case sequence for the whole 2m of the human genome requires a data warehouse (pictured) to store the information electronically. This should give a good idea of just how efficient DNA is at storing information and why it needs to be so.. shapes and patterns. 조연우. Contents. DNA. DNA origami. The application of DNA origami.
