  • The Metabolism Hypothesis

    Replication, first, came about because RNA was formed. This occurred because organic molecules on Earth were able to form ribonucleotides from the assistance of a clay catalyst. Eventually, these ribonucleotides formed RNA, which, through time, began to fold and replicate itself. As replication got faster, RNA's started to attract amino acids and hold them together. Bonds started forming, and proteins were able to be produced. As more years passed, a lipid membrane enclosed the structure to…

  • The Origin Problem In Research

    researchers discovered DNA relies on proteins for transcription and translation, but functional proteins cannot form without the information stored in DNA. The solution to the problem seemed to lie in RNA, the mediator between DNA and proteins. It has been discovered that RNA can catalyze many reactions, and RNA might catalyze its own replication. If RNA could self-replicate natural selection or some other mechanism could act to create a more complex RNA. If this were the case than RNA might…

  • Alkaline Phosphatase Research Paper

    Alkaline phosphatase (AP) is a homodimeric enzyme complex that is commonly found in a wide range of organisms, from bacteria to all tissues of the human body. AP is a zinc metalloenzyme (1), in which metal ions play a key role in the regulation of catalytic activities and stabilization of enzyme-substrate complex. As proposed by Gettins and Coleman using NMR studies (10), each active site of AP comprises of three metal binding sites, which acknowledged as M1, M2, and M3. Two zinc ions bind to…

  • Protein Structure Hypothesis

    This early work used what are called local methods to calculate related mutations from protein sequences, however suffered from indirect false correlations that result from treating every pair of residues as independent of all alternative pairs.In 2011, a distinct, and this time world applied mathematics approach, demonstrated that predicted coevolved residues were adequate to predict the 3D fold of a protein, providing there are enough sequences out there.The method, EVfold, uses no homology…

  • Neoplasm Case Study

    cancer has been made evident the use in studying this circadian clock gene is quite clear and the need for a more solid grasp on its mechanism is necessary to understand a possible treatment in cancer. For this experiment we chose a knockdown experiment through RNA interference (RNAi) of the timeless gene in order to observe the phenotypic outcome in planarian when this gene is absent. This is a known procedure for disturbing the function of genes in planarian (4). We made a double stranded…

  • Cyanoethoxy Research Paper

    2-cyanoethyl carbonochloridate (S.27b ) or 1-((2-cyanoethoxy)carbonyl)-3-methyl-1H -imidazolium chloride (S.27c) (Figure X.X.X), which were synthesized by the modified procedures of Merk et al. (2000) and Wielser et al. (1996). Deproetection was accomplished under nonprotic conditions using non-nucleophilic strong base 1,8-diazabicylco [5.4.0]undec-7-ene (DBU). The mechanism of deprotection follows -elimination pathway. Another advantage of this protection strategy is that the deprotection of…

  • Deoxyribonucleic Acid Research Paper

    Deoxyribonucleic acid consists of a phosphate and deoxyribose backbone, and four different nitrogenous bases. These bases are adenine, guanine, cytosine, and thymine. Ribonucleic acid, the molecule formed in the transcription of DNA, is made up of phosphate, ribose, and adenine, guanine, cytosine, and uracil. The backbone of DNA consists of a phosphate bonded to a deoxyribose molecule. Deoxyribose is a sugar containing five carbons, and it is called deoxyribose as it is missing an oxygen atom on…

  • Advantages And Disadvantages Of Tri-O-Acetyloride

    Under oxidative conditions, certain nucleobases (for example, adenine and cytosine) can form N-oxides. Also, the C8 position of guanosine is vulnerable to hydrolytic attack under either strongly acidic or strongly alkaline conditions. The 5,6 double bond of pyrimidine nucleosides also reacts with halogens and halohydrins to give the corresponding addition products (Shabarova and Bogdanov, 1994). Selected examples of the side reactions that occur during oligonucleotide synthesis are given below.…
