By Preeti S Salve KLE College of Pharmacy Belagavi A constituent Unit of KLE Academy of Higher Education and Research Nehru Nagar Belagavi 590 010 Karnataka India Phone. DNA. Deoxyribonucleic acid. Complex molecule found in the nucleus of cells and in small quantities in mitochondria and chloroplasts. DNA (Deoxyribonucleic Acid). discovery/history. 1950’s. x-rayed by Rosalind Franklin. 2. Nucleic acids/ Polynucleotide. 3. Types of nucleic acids. Basic unit of nucleic acids. Made up of 3 basic components. Pentose sugar. Organic base. Phosphate group. 1.1 Pentose sugar. Ribose. or . Dr. . Sahar. Al . Shabane. Nucleic acids.  are biopolymers, or large . biomolecules. , essential for all known forms of . life. . Nucleic acids, which include . DNA.  (deoxyribonucleic acid) and . 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). 1-deoxyribonucleic acid (DNA). 2-Ribonucleic acid (RNA. Nucleic. Acids. Structure: Nucleotide. Monomer : . Nucleotide. A pentose sugar molecule .. 2.A phosphate group .. 3.A nitrogenous base .. Monomer : . 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.. 1. Heredidity. Heredity. is the transfer of characteristics anatomical as well as biochemical, from generation to generation. . The transmission of hereditary information from one generation to another takes place in the nucleus of the cell, . Shabane. Nucleic acids.  are biopolymers, or large . biomolecules. , essential for all known forms of . life. . Nucleic acids, which include . DNA.  (deoxyribonucleic acid) and . RNA. The Double Helix (DNA). Structural model:. Model proposed by Watson & Crick, 1953. Two sugar-phosphate strands, next to each other, but running in opposite directions.. Specific Hydrogen bonds. occur among bases from one chain to the other:. Each nucleic acid has its own unique sequence of bases that carries the genetic information from one cell to the next.. Learning . Goal . Describe the primary structures of DNA . and RNA. .. Nucleic Acid Structure. Pgs.:. 9-10. Heading: . Nucleic Acids. Homework:. . SILENTLY complete the Do First and glue on page 9.
