PPT-RNA and Nucleic Acid Reactions

C483 Spring 2013 1 Which is not a difference between RNA and DNA A RNA is more prone to basic aqueous hydrolysis B RNA contains uracil DNA usually does not C RNA cannot form helices . Jasmin. . Šutković. Organic Chemistry – FALL . 2015. Lecture 1. 0. Nucleic acids and protein synthesis. CHAPTER OUTLINE. International University of Sarajevo . 22.1 Nucleosides and Nucleotides. RNA. DNA . RNA. RNA. ( RIBONUCLEIC ACID ) . SINGLE STRANDED NUCLEIC ACID.. RNA CONTAINS RIBOSE (HYDROXYL GROUP ATTACHED TO THE PENTOSE RING) .. 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.. CHM . 341. Suroviec. . Fall . 2016. I. . Nucleotides, Nucleic Acids and Bases. Bases. Planar, aromatic, heterocyclic. Purine (2 rings). Pyrimidine (1 ring) . Adenine (A). Guanine (G). Thyamine (T). 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). 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. Presented by . YASMIN. . BANU. Dept Of Biotechnology. INTRODUCTION. The two strands of a DNA molecule are . denatured.  by heating to about 100°C = 212°F (a to b). At this temperature, the . complementary base pairs. 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. RNA. During protein synthesis certain specific regions of DNA (the genes) are copied into a polynucleotide of a chemically and functionally different type known as . ribo. nucleic acid.. RNA is a nucleic acid polymer consisting of nucleotide monomers that acts as a messenger between DNA and . A crucial property of the double helix is the capacity is to separate the two strands without disrupting the covalent bonds that form the . poly nucleotides . and at the very rapid rates needed to sustain genetic functions.. What Are the Molecules of Heredity?. . . After scientists became aware of the differences in amino acid sequences, their next quest was to determine how cells know which proteins to synthesize out of the extremely large number of possible amino acid sequences. The answer is that an individual gets the information from its parents through . Asst. . lec. . Mariam Ahmad Ali . Introduction to Viruses. Viruses are the smallest infectious agents (20 -300 nm in diameter), containing only one kind of nucleic acid (RNA or DNA) as their genome. The nucleic acid is encased in a protein shell, which may be surrounded by a lipid .
