Data Analysis Of DNA By The Standard Crystallographic Method

Sedna is a planetoid that is the furthest known object in our solar system. It was discovered on November 14, 2003. On average, Sedna is about 507 AU from the sun. Sedna's radius is probably about 890 kilometers. It can be found 13 billion kilometers away. Sedna is 939 AU from the sun at its most distant, meaning it is about three times further away from the sun than Pluto. It's distance from Earth on average is 938 AU. Astronomers to not yet know what Sedna is made of. Sedna orbits the sun, but it takes 11,000 years for Sedna to complete its orbit. Sedna is possibly the first detection of the theorized Oort cloud. The Oort cloud is hypothesized to supply comets that pass by Earth. However, Sedna is ten times closer than astronomers predicted the Oort

When we speak of values, there can be a broad spectrum of subjects from the generations that still attend our church to the core values or the DNA of our congregation. For example, we value every member from various generations that still attend service on a regular basis. There are still a few builders (1931–1945), several baby boomers (1945–1964), the bulk of the congregation are Generation X (1965–1985), and the millennials (1986–2005).

The great race to discover the structure of DNA started with Gregor Mendel and his observation that parents are offspring have similar traits. They knew that if they could find the backbone of life it would help to explain how life itself would work. But that was about all that was known. How was DNA structured? This is was one of the most common early questions. But it became obvious that it was too broad. As advancements were made in this category questions were asked like, “why was the x-ray structure different in the summer than in the winter?”, “What and how are the base pairs connected if they are?” and many other questions. This race was very important to many people because they know that the discovery of the structure of DNA would

The study of geologically ancient DNA began in 1984 with Russell Higuchi and a handful of other scientists. Hoping to determine whether ancient DNA survived and could be retrieved from samples of preserved soft tissue, they examined samples of dried muscle taken from a museum specimen of the quagga. Their attempts to extract genetic material were successful, and the samples yielded slightly less than 1% of the DNA that would have been yielded by fresh muscle; from this, they successfully sequenced two pieces of mitochondrial DNA (Higuchi and others, 1984).

DNA polymerases are vital in how an organism can sustain life. DNA polymerases are enzymes that synthesize DNA molecules from deoxyribonucleotides and are accountable for DNA replication. They are absolutely critical for DNA replication and will typically work in sets so that they can create two identical sets of DNA strands from one single strand of DNA. DNA polymerase will catalyze the reaction: deoxynucleoside triphosphate + DNAn diphosphate + DNAn+1. DNA polymerases are extremely important because each time a cell divides, DNA polymerases have to be involved in order to assist in duplicating the cell’s DNA. Duplication of a cell’s DNA allows for the daughter cell to get a copy of the genetic information so that it can carry to multiple generations after. Helicase unwinds DNA so that it separates the two strands making them each single stranded, which will be used as “templates for replication” (Mandal, 2014). DNA polymerase becomes important as now it can add nucleotides to the 3’ end so that the 5’ to 3’ will be extended. DNA polymerase is a very precise and accurate process although, a mistake of one in a billion base pairs copied can be made. DNA polymerase proofreads the DNA so that the base pairs can be corrected if need be. As a visual, “DNA polymerases are shaped like a hand with fingers, palm and thumb subdomains” (Benoît).

In the 1930s and 1940s, scientists were determined to identify the fundamental concept whether DNA, RNA, or proteins were the genetic material in organisms, and were leaning towards proteins as they are the most molecularly diverse of the three. At the time, DNA was considered too simple to compose the genetic material as it consisted of only four unique base pairs. These investigations were initiated from research completed by Fred Griffith in 1928, in which he was studying the bacterium Streptococcus pneumoniae through injections into mice. Griffith sought to use mice as his species for determining the pathogenicity of the bacteria. In Griffith’s experiment, mice were injected with the following samples and recorded pathogenic or

Understanding ideas at a macroscopic scale is simple. Looking at a clock, observing and understanding the movements of the hands over the numbered surface are, in essence, all one requires to use the device. In order for innovation to occur, it is imperative to understand the inner workings of the device on a microscopic scale to modulate its properties. Such is the case for many innovations in science, from the heat engine to penicillin, and is no different for biological advancements. Like the seed of a plant, the understanding of the structure of DNA constitutes the basis of all life, establishing a foundation upon which explanations of increasing complexity can be developed. In the eyes

The Encyclopedia of DNA Elements (ENCODE) is a project designed to compare and contrast the repertoire of RNAs produced by the human cells and cross verify with other methods like NGS. After a five year start-up since the beginning of the ENCODE project just 1% of the human genome has been observed and what was achieved was just the confirmation of the results of previous studies.

The tannase structure was solved by MIRAS (multiple isomorphous replacement anomalous scattering) using PHENIX software suite (Adams et al., 2010). The initial phases were calculated using five heavy-atom derivative crystals data sets and obtained the figure of merit (FOM) of 0.37 at resolution of 3.5, which acted as the quality control for the phase estimated. Then, the initial phases with weak FOM were refined by electron density and phase modification. Then, an initial model of tannase structure was generated using the automated model building protocol. The initial model consist 89% of the residue in the misaligned unit built in the tannase structure. The initial model produced was first inspected and adjusted manually using COOT

The as-prepared pristine ZnO:P and ZnO:In3+ samples were characterized via X-ray diffraction (XRD) using Cu-Kα radiation (λ= 1.54056 Å) in the 2θ range of 20°-80° [Bruker Advanced-D8 powder X-ray diffractometer]. The scanning speed and steps were 2°/ minute and 0.02° of 2θ respectively. The XRD data were analyzed by Rietveld refinement technique using FULLPROF program to confirm the phase formation as well as to obtain the lattice parameters, space group and crystal system [2]. The microstructures and crystal structures of the nanoparticles were obtained using Transmission Electron

CO2 adsorption capacity is defined as a measure of an adsorbent’s capability or potential to adsorb CO2. It is expressed in terms of number of moles of CO2 that a unit mass of an adsorbent adsorbs under equilibrium conditions. The CO2 adsorption isotherms for MCM-41-30, MCM-41-30-AP-9-85-0.5 and MCM-41-30-TP-9-75-0.3 at 30 °C are presented in Figure 6(a). The CO2 adsorption isotherms for amine tethered samples exhibit a steep nonlinear concave shape due to the strong interactions between carbon dioxide molecules and amine moieties. In contrast, MCM-41-30 exhibits a less steep isotherm indicating that pure silica interacts with CO2 only by physisorption and hence lacks sufficient strong affinity towards CO2. Therefore, it is clear that the

One of the advantages of this technique is that, the x-ray sources it employs, which include Al K (1486.6 eV) and Mg K (1253.6 eV) have very narrow x-ray lines below 0.9ev [1]. Therefore, this sources provide a good energy resolution hence making this technique applicable in many areas. Also, the electrons of the elements present in the solid surface are emitted at characteristic energies thus many elements can be identified easily. Moreover, XPS technique allows identification of all chemical states at any given element through quantification of the high resolution peaks [2].
