PPT-17.2 Primary Structure of Nucleic Acids

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. 36. Which . of the following statements best describes the structure of DNA. ?. A. . Two strands of proteins are held together by sugar . molecules. , . nitrogen bases, and . phosphate groups.. B. . 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). polymers. four major classes of biologically important organic molecules: . carbohydrates. lipids. proteins . (and related compounds). nucleic acids . (and related compounds). Discuss hydrolysis and condensation, and the connection between them.. 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.. Biomolecules. Organic molecules made up of:. Carbon. Hydrogen. Nitrogen. Oxygen. a. nd sometimes Phosphorus. LATIN 101. Poly = . Many. Mono = . O. ne. Hydro = . Water. . (actually Greek). Synthesis = . Consists of 5 carbon sugar, nitrogen base, and phosphate group. Repeating unit that makes up DNA, RNA, and ATP (energy for cells). What is a nucleic acid?. Store genetic material (DNA). Transfer genetic code (RNA). Shabane. Nucleic acids.  are biopolymers, or large . biomolecules. , essential for all known forms of . life. . Nucleic acids, which include . DNA.  (deoxyribonucleic acid) and . RNA. A . peptide bond . is an amide bond that forms when the —. . COO. −. group of one amino acid reacts with the —. . NH. 3. +. group of the next amino acid.. The linking of two or more amino acids by peptide bonds forms a . Pgs.:. 9-10. Heading: . Nucleic Acids. Homework:. . SILENTLY complete the Do First and glue on page 9. SILENTLY update notebook. Do First. DO FIRST (PG 9). Which biomolecule…. Makes up hair, nails, and feathers? c. Provides cells with cushioning. What are nucleic acid ?. Linear polymers of . nucleaotides.first. isolated by . Miescher. (. 1871). Each nucleotide consist of 3 components . 1. . purine. or . pyrimidine. . nucleobase. BSc 3. rd. year . AMINO ACIDS. C. lassification of amino acids .

MACROMOLECULES. made by . polymerization. -large compounds built by joining smaller ones together. . Smaller units (subunits) are called . 1. Nucleic . Acids. Biochemistry 3070. Biochemistry 3070 – Nucleic Acids. 2. Historical Summary of the Discovery of DNA. The complexity of living processes require large amounts of information.. In the 19. Proteins are naturally-occurring biopolymers comprised of amino acids. . The biological function of proteins is inherent in their three dimensional structure.. All the information required for correct folding of the protein into its functional .
