DNA A double stranded, helical nucleic acid. Sort by: Top Voted. 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. This emergent property is a direct consequence of the double‐helical character of the molecule. Our mission is to provide a free, world-class education to anyone, anywhere. Different Types of DNA in Different Organisms 8. In prokaryotes it occurs in nucleoid and plasmids. rRNA directs the translation of mRNA into proteins. I thought that by showing images of structures and animations of how things fit together and what processes occured it would benefit the students and help them to understand DNA structure and function. Figure 8.6 Structure of DNA, as illustrated by a composite of different models (right). Function . DNA Structure and Function Powerpoint Presentation . Ribonucleic acid (RNA) is a type of molecule that consists of a long chain of nucleotide units. Experiments in the 1950s showed that DNA is the hereditary material ; Scientists raced to determine the structure of DNA ; 1953 - Watson and Crick proposed that DNA is a double helix; 3 Structure of Nucleotides in DNA. FUNCTION OF DNA (EXPL 1) 1. DNA: The Master Molecule Video. All Time. Updated: Feb 22, 2018. ppt, 2 MB. 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. What is DNA? 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. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. tRNAs are an essential component of translation, where their main function is the transfer of amino acids during protein synthesis.
