DNA REPLICATION Objectives: 1
Lecture 1 DNA REPLICATION Objectives: 1. To understand the replication process and where it occurs in the cell cycle. 2. To describe the Replication Fork, Okazaki fragments and the enzymes involved in the unwinding process and replication. 3. To understand how DNA polymerase initiate the synthesis of new strands. 4. To define Telomeres and Telomerase and their clinical significance. Gene expression also called protein expression or often simply expression: is the process by which a gene's DNA sequence is converted into the structures and functions of a cell. The amount of protein that a cell expresses depends on: 1. the tissue, 2. the developmental stage of the organism 3. and the metabolic or physiologic state of the cell. DNA replication or DNA synthesis is the process of copying a double-stranded DNA strand, prior to cell division. The two resulting double strands are identical (if the replication went well), and each of them consists of one original and one newly synthesized strand. This is called semi conservative replication. 1 Prof. Dr. H.D.El-Yassin 2013 Lecture 1 The process of replication consists of three steps, initiation, replication and termination. 1. Prokaryotic replication Basic Requirement for DNA Synthesis 1. Substrates: the four deoxy nucleosides triphosphates are needed as substrates for DNA synthesis. Cleavage of the high-energy phosphate bond between the α and β phosphates provides the energy for the addition of the nucleotide. 2. Template: DNA replication cannot occur without a template. A template is required to direct the addition of the appropriate complementary deoxynucleotide to the newly synthesized DNA strand. -

Folic Acid Antagonists: Antimicrobial and Immunomodulating Mechanisms and Applications
International Journal of Molecular Sciences Review Folic Acid Antagonists: Antimicrobial and Immunomodulating Mechanisms and Applications Daniel Fernández-Villa 1, Maria Rosa Aguilar 1,2 and Luis Rojo 1,2,* 1 Instituto de Ciencia y Tecnología de Polímeros, Consejo Superior de Investigaciones Científicas, CSIC, 28006 Madrid, Spain; [email protected] (D.F.-V.); [email protected] (M.R.A.) 2 Consorcio Centro de Investigación Biomédica en Red de Bioingeniería, Biomateriales y Nanomedicina, 28029 Madrid, Spain * Correspondence: [email protected]; Tel.: +34-915-622-900 Received: 18 September 2019; Accepted: 7 October 2019; Published: 9 October 2019 Abstract: Bacterial, protozoan and other microbial infections share an accelerated metabolic rate. In order to ensure a proper functioning of cell replication and proteins and nucleic acids synthesis processes, folate metabolism rate is also increased in these cases. For this reason, folic acid antagonists have been used since their discovery to treat different kinds of microbial infections, taking advantage of this metabolic difference when compared with human cells. However, resistances to these compounds have emerged since then and only combined therapies are currently used in clinic. In addition, some of these compounds have been found to have an immunomodulatory behavior that allows clinicians using them as anti-inflammatory or immunosuppressive drugs. Therefore, the aim of this review is to provide an updated state-of-the-art on the use of antifolates as antibacterial and immunomodulating agents in the clinical setting, as well as to present their action mechanisms and currently investigated biomedical applications. Keywords: folic acid antagonists; antifolates; antibiotics; antibacterials; immunomodulation; sulfonamides; antimalarial 1. -

Skirball Center for Chemical Biology and Proteomics Salk Institute for Biological Studies Date Defended/Approved: August 12, 2021 ii Abstract The RNA World hypothesis proposes that the early evolution of life began with RNAs that can serve both as carriers of genetic information and as catalysts. Later in evolution, these functions were gradually replaced by DNA and enzymatic proteins in cellular biology. I start by reviewing the naturally occurring catalytic RNAs, ribozymes, as they play many important roles in biology today. These ribozymes are central to protein synthesis and the regulation of gene expression, creating a landscape that strongly supports an early RNA World. -
Health Effects Support Document for Perfluorooctanoic Acid (PFOA)
United States Office of Water EPA 822-R-16-003 Environmental Protection Mail Code 4304T May 2016 Agency Health Effects Support Document for Perfluorooctanoic Acid (PFOA) Perfluorooctanoic Acid – May 2016 i Health Effects Support Document for Perfluorooctanoic Acid (PFOA) U.S. Environmental Protection Agency Office of Water (4304T) Health and Ecological Criteria Division Washington, DC 20460 EPA Document Number: 822-R-16-003 May 2016 Perfluorooctanoic Acid – May 2016 ii BACKGROUND The Safe Drinking Water Act (SDWA), as amended in 1996, requires the Administrator of the U.S. Environmental Protection Agency (EPA) to periodically publish a list of unregulated chemical contaminants known or anticipated to occur in public water systems and that may require regulation under SDWA. The SDWA also requires the Agency to make regulatory determinations on at least five contaminants on the Contaminant Candidate List (CCL) every 5 years. For each contaminant on the CCL, before EPA makes a regulatory determination, the Agency needs to obtain sufficient data to conduct analyses on the extent to which the contaminant occurs and the risk it poses to populations via drinking water. Ultimately, this information will assist the Agency in determining the most appropriate course of action in relation to the contaminant (e.g., developing a regulation to control it in drinking water, developing guidance, or deciding not to regulate it). The PFOA health assessment was initiated by the Office of Water, Office of Science and Technology in 2009. The draft Health Effects Support Document for Perfluoroctanoic Acid (PFOA) was completed in 2013 and released for public comment in February 2014. -
