PPT-Nucleic acids Structure

Function amp Repair Lecturer 7 Dr Shaimaa Munther Organelles of the cell Living organisms are made up of cells Each of these cells have a viscous substance called cytoplasm. NA ThiR structure has novel f8tUIW which 8IX3 of considereblc biological intewst A structure for nucleic acid has already been proposed by p8uling and Corey They kindly m8de their manuscript 8vailablo to us in 8dvence of publication Their model conht 2. Proteins. Proteins are polymers made of monomers called amino acids. All proteins are made of 20 different amino acids linked in different orders. Proteins are used to build cells, act as hormones & enzymes, and do much of the work in a cell. 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.. Attractive force between particles of the same kind. ____________________. Attractive force between unlike substances. _______________________. In a mixture of water and cool-aid which would be the solute and which would be the solvent?. Biochemistry-Macromolecules 4 types Carbohydrates Lipids Proteins Nucleic Acids Carbohydrates Function of Carbohydrates Energy source!!! Energy is stored in the C-H bonds Plant Structure Cellulose is a carbohydrate found in the cell wall of plants 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. ..
