The Powerpoint to accompany making DNA models using gummy bears, cocktail sticks and strawberry lances. ... ppt, 2 MB. S.S.R.Medical College, Structure of DNA , Functions and Properties. Functions of DNA It is a long chain polynucleotide which exist in a regular conformation like a double-chain DNA although some viruses [e.g., reoviruses and wound tumour virus) have double stranded RNA. A nucleosidec… Figure 8.6 Structure of DNA, as illustrated by a composite of different models (right). DNA Nucleotides. Functions of DNA and summary of structure DNA consists of four bases—A, G, C, and T—that are held in linear array by phosphodiester bonds through the 3' and 5' positions of adjacent deoxyribose moieties. 9. DNA RNA ATP ABC Macromolecules Review 2006-2007 Carbohydrates Structure / monomer monosaccharide Function energy raw materials energy storage structural compounds Examples glucose, starch, cellulose, glycogen glycosidic bond Lipids Structure triglycerides, steroids, phospholipids, waxes Function energy storage membranes Sex Hormones Insulation/protection Examples Saturated & … (a) The sugar-phosphate backbones are on the outside of the double helix and purines and pyrimidines form the “rungs” of the DNA helix ladder. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Pol I replicates DNA with high fidelity. South Valley UniversitySouth Valley University. Lecturer of biochemistryLecturer of biochemistry official orders to work structure of DNA again They needed more information, they needed to figure out how the four components of DNA went together.Erwin Chargaff was the key. Preview. Replication. Nucleic Acid is a category of biomolecules that includes DNA, RNA, and ATP. This is the currently selected item. Although this double‐helical character is not required by the complementarity per se – a simple straight ladder structure would fulfil this function just as well – it does impart crucial physical and chemical properties to the polymer. With the discovery of the molecular structure of the DNA. MedicineFaculty of Vet. DNA structure and function. Report a problem. Mauritius Z-DNA; Left handed double helical structure winds to the left in a zig- zag pattern. News; Many are downloadable. For example, the chicken ovalbumin gene contains eight exons and seven introns distributed over 7700 base pairs (7.7 kilo-bases or 7.7 kb) of genomic DNA. Ppt video online download. ONLY EUKARYOTIC CELLS HAVE A NUCLEUS! DNA-and-RNA. Dna structure. Structure of DNA: DNA or deoxyribonucleic acid is a helically twisted double chain polydeoxyribonucleotide macromolecule which constitutes the genetic material of all organisms with the exception of rhinoviruses. double helix in 1953, researchers turned to the structure of ribonucleic acid (RNA) as the next critical puzzle to be solved on the road to understanding the molecular basis of life. The B‐DNA structure, that proposed by Watson and Crick , is most stable at high humidity, but ... An often overlooked function of DNA in a cell nucleus or bacterial nucleoid is that it can act as an energy store for facilitating the transit of DNA and RNA polymerases. Now that we have learned about the structure of DNA and how it makes copies (replicates), we will now learn why DNA is called the "blueprint of life". E- DNA; Extended or eccentric DNA.
