    Zinc fingers and oxidative DNA damage

    Can zinc fingers be used to solve the oxidative DNA damage problem? theoretically? "By attaching zinc fingers which determine where transcription factors bind to endonuclease, which break DNA strands, homologous recombination can be induced to correct & replace defective/undesired DNA sequences"

    The XRD pattern of Zinc oxide and zinc oxide in acrylic acid

    the XRD pattern of Zinc oxide and zinc oxide in acrylic acid ! I did XRD analysis of zinc oxide, and its peaks are at 31.7, 34.4, 36.2, 47.5, 56.6, 62.9 and 67.9 (2-theta degree). further, I did XRD of zinc oxide dispersed in acrylic acid/IPA. but it's weird ! Why I could got some peaks at...

    How Does Copper Sulfate Affect the Reaction Between Zinc and Hydrochloric Acid?

    I'm having some trouble understanding what happens when Zinc and Hydrochloric acid are reacted with Copper Sulfate as a catalyst. I *think* the Copper ion gets electrons from the zinc and turns into straight copper which leaves zinc free to react with the chlorine to form zinc chloride. Does...

    Latent Heat of Zinc Sublimation at 600K

    The Latent Heat of sublimation for zinc(atomic mass = 65.4 u) at 600k is 1,990,000 j/kg. Assume that the zinc vapor can be treated as a monatomic ideal gas and that the volume of one kilogram of solid is negligible compared to that of the vapor. What percentage of the latent heat serves to...

    Investigating Redox Reactions: Zinc Oxidation

    I'm trying to find out what type of reaction this is. a drop of water is added to a small pile of chemicals in a dish, after a few seconds, a blue flame and smoke is produced. NH4NO3 reacts to form (with chlorine as catalyst) N2O and water the experiment is called oxidation of zinc, so...

    Zinc difecient Mother and birth weight problem

    Using a study of zinc deficient mothers a double blind test was conducted using a placebo group and a test group. Using a .05 significance level to test a claim that zinc supplimentation does increase weight at birth. The weights are measured in grams. How can I test to see if the zinc...

    Oxidation - Reduction with copper and zinc

    Hello, In a lab experiment, we filled 2 wells of a culture plate, one of them had 1.0 M CuSO4 and a piece of zinc metal, and the other well had 1.0 M ZnSO4 and a piece of copper metal. My question is: Which well has the reduced form of zinc and the oxidized form of copper? I know that...

    Zinc Coating: What Makes it Ideal for Steel Protection?

    Why Zinc is so commonly use coat metals such as steel? I know that its a good corrosion resistant metal to use but what properties of zinc make it good to use under normal atmospheric conditions? Does it have to do with the oxide layer that it forms around it?

    How Do Copper, Iron, Aluminium, and Zinc Correlate in Properties and Uses?

    The question basically states write a brief overview of the correlation between the properties and uses for copper, iron, aluminium and zinc. Now I know this sounds like a simple research task, it's supposed to relate to periodic trends and their placing on the table. It's in this area that...

    Does Zinc React with Acetic and Phosphoric Acid?

    Does zinc react with both acetic acid (CH3COOH) and phosphoric acid (H3PO4)? I can't figure out the chemical equations for them and am wondering if no reactions occur. Thanks.

    Does Zinc Tend to Lose Electrons When in Contact with Negatively Charged Metals?

    If a metal(Cu) is negatively charged, and is put to touch an another neutral metal(Zn), the extra charges are shared by both metal. But, doesn't zinc tend to lose e-?

    Solving Zinc Carbon Cell Equation: 2MnO2 + 3H2

    The hydrogen liberated at the cathode would coat the electrode so polarises the cell. And manganse (IV) oxide is used as a depolariser. I got an equation in my notes: 2MnO2 + 3H2 --> 2MHO(OH) + 2H2O. But evidently the oxygen doesn't balance. I tried looking on the internet but still no...

    Solving Corrosion & Heat Transfer Problems on Steel Vat Plated with Zinc

    I have a problem that I need to solve that is quite extensive it boils down to this. I have a steel vat that's been plated with zinc and its being used to store sulfuric acid. I have to find corrosion rates, heat transfer and thermal stresses, elastic and plastic deformation problems, hydrogen...

    Pentacoordination of Zinc: A Possibility or a Myth?

    Hello, I've heard rumors (frankly, not rumors, evidenced by some scientific papers), that zinc(II) ion has coordinated five ligands, four at a plane, and the fifth from top, to form a tetragonal monopyramidal environment. I have some doubts about this, because zinc (II) ion has d10...

    Equation Reactions: Solid Zinc + Sodium Hydroxide

    I'm having trouble with sample AP Equation writing questions such as; solid zinc hydroxide is treated with concentrated sodium hydroxide solution. The sheet my teacher provided does not cover this reaction and many others is there any material out there that tells what will happen in most reactions
