Does The Article Watching DNA Polymerase And Make A Phosphodiester Bond

597 Words3 Pages

Journal Summary 2

I found the article, “Watching DNA polymerase n make a phosphodiester bond” (Nakamura, et al.) very interesting. Their research into the different transition states of DNA replication really gave me a chance to think about more than just the “big picture” points in DNA synthesis and look closer at the details.
The goal of the research was to visualize the chemical reaction of DNA synthesis. The researchers used x-ray crystallography to follow the bond formation and structural changes associated with DNA replication reactions. These transition states have never been visualized previously. They catalysed the reaction by using DNA polymerase (Pol) and were able to extend the use of flash freeze technology. This allowed them to see the reaction in real time, with the help of X-ray crystallography. Due to this new technique, they observed additional transitional states previously unexplored as well as suggesting a third magnesium ion is involved in the reaction. They believed and proved, that by using their technique, intermediate states …show more content…

The researchers not only believed that this technique is valuable for visualizing already known transition states in DNA synthesis, but that it would show that there are additional transition states that, due to short reaction times and high energy, have no previously been seen. The researchers also identify a third magnesium ion that stabilizes the new bond in the intermediate state. This add information to the two metal ion dependent mechanism that is believed to be used by DNA and RNA polymerases as well as many nucleases. I think this research is important because it not only documents new techniques that may be helpful in other areas of research, but it takes a fine tooth comb through the bond formations in DNA

After the reaction it was white and brittle, like a burnt piece of paper. It no longer displayed its original qualities. Since the magnesium reacted with oxygen to form MgO, the mass of MgO should be greater than that of the magnesium. Did this occur? If not, why?

Grignard is a reaction that is crucial to forming the new carbon-carbon bond. This is a two-part lab that teaches new techniques; the purpose of this lab is to introduce realistic organic synthesis and apply acid workup to produce triphenylmethanol. A Grignard reaction is characterized by the addition of a magnesium halide (an organomagnesium halide) to an aldehyde or a ketone in order to form a secondary or tertiary alcohol. These reactions are helpful because they serve as a crucial tool in performing important carbon-carbon bond-forming reactions (Arizona State University, 2018). This experiment aimed to observe the mechanisms of a Grignard reply to synthesize triphenylmethanol from benzophenone using phenylmagnesium bromide as the Grignard reagent.

However it did excited some and inspired further research at the nature of DNA. Such as the relative composition or bases that contain DNA, also X-ray studies and its structure. Francis Crick and James Watson Were in England in 1953 when they discovered DNA contained a two of a kind sequences of complementary bases. Encodes in genes are ordered by DNA. Hershey-Chase:

Wachtershauser says that amino acids could have been created deep in the earth’s crust and these amino acids were brought up with other hydrothermal material into colder waters. Experimental research shows that minerals inside hydrothermal vents have the same properties to enzymes and are able to create simple organic molecules such as methanol and formic acid out of dissolved carbon dioxide in the water. A man by the name of Joan Oro found that the nucleotide base adenine can be made from hydrogen cyanide and ammonia in a water solution. His experiment created a lot of adenine, the molecules of which were formed by 5 molecules of hydrogen cyanide. Experiments done later showed that the other RNA and DNA nucleobases can be created with simulated prebiotic chemistry with a reduced

Introduction In the book The Double Helix, by James D. Watson, it explains the journey for James Watson and Francis Crick on finding the deoxyribonucleic acid, or better known as DNA, structure. It was a great book containing a lot of information on the journey. In the book, it contained great information on James Watson's life, Francis Crick's life, reasons they wanted to find the DNA structure, important people to the discovery, and the journey on finding the DNA structure. (Watson, 7-223)

The Double Helix: Watson and Crick and the Forgotten Names James Watson and Francis Crick were at best interpreters in a time of constantly-expanding scientific knowledge. Despite seeming to have intellect and experience enough to make their own discoveries, the real credit for the discovery of the structure of DNA lies with the three scientists who made the most contributions to the work: Linus Pauling, Rosalind Franklin, and Maurice Wilkins. Their work in the field of DNA shed light onto the truth value of various theories that would have remained mysteries except for their accomplishments. Moreover, Watson and Crick had no qualms about stealing the work and ideas of others, nor did they have any notions of respecting their peers’ wishes, and they openly admitted to it in this text. All Watson and Crick cared about was potential glory, and the points below will outline why they are deserving of none.

In early 1950’s, James Watson and Francis Crick have also investigated the structure of DNA. However this time, the structural model of DNA is formed. On their investigation, they compiled and analyzed all the existing study about the structure of DNA rather than conducting an experiment in a laboratory. Some works that they used as added idea in creating the model are the Chargaff’s rule and Franklin’s “X-ray Crystallography image of DNA.” Their final output is a “DNA Double Helix Model.”

His findings are considered to be the foundation of modern chemistry as well as the basis for what is known today as molecular biology. The main aim of Pauling’s scientific career would be to discern the underlying structure of all matter, and to understand how that structure determines the substance, composition, and even the function of objects and living organisms alike. He sought the “secret of life,” as he put it: reducing the simplest creature and the most complex to their elements, which are common not only to both amoeba and biochemist, but to plankton and poet, dandelion and dandruff, lizard and linguine. He was out to answer the sorts of questions that puzzle a wondering child, and that stump the parents and teachers whom the child annoys with his endless importunate curiosity. When the 1940’s came around he paused his work and volunteered his services to the government during World War 2.

Many people are familiar with the spiral staircase appearance of DNA. The twisted pieces on the outside of the ladder are called the sugar phosphate backbone. The rungs of the latter consist of nitrogenous bases called Adenine, Thymine, Guanine, and cytosine with Adenine always pairing with thymine and guanine always pairing with cytosine. A phosphate group, a sugar, and one of the four nitrogenous bases bond to create a nucleotide which makes up DNA. In fact, DNA stands for Deoxyribonucleic acid with nucleic representing the nucleotides in DNA.

Martha Cowles Chase, an American Geneticist, was known to be with Hershey during the conducting of their “Hershey-Chase Blender” experiment. With Chase, Hershey found a way to determine the role each of the phage components played in the process of replication. In their experiments done in 1951 and 1952, Hershey used radioactive phosphorus to tag the DNA and radioactive sulfur to tag the protein. (note that DNA contains no sulfur and the protein contains no phosphorus.) Hershey and Chase then allowed the marked phage particles to infect a bacterial culture and to begin the process of replication.

Sophia Greenwood Mrs. Rupertus 518-02 14 May 2023 Rosalind Franklin Rosalind Franklin was an innovative female scientist and most renowned for her studies with the double helix structure of deoxyribonucleic acid (DNA) strands. Franklin was the first person to determine the arrangement of molecules in DNA using a technique called x-ray diffraction. X-ray diffraction is a method used to analyze the structure of materials at a molecular level and is a non-destructive procedure. (Encyclopedia Britannica - Britannica.com). Scholars today argue that James Watson and Francis Crick stole Franklin’s studies on the double helix, stating Watson and Crick used her unpublished data without Franklin’s permission or knowledge.
