Protein extractions from unidentified fish samples were separated according to the molecular weights by SDS polyacrylamide gel electrophoresis. Since some of these proteins are shared between fishes, phylogenetic evaluation was reached. Western blot analysis was used to identify four unknown species of aquatic animals via comparison of actin/myosin bands. According to the results of this assay, the best estimate is that the unidentified aquatic animals are specimens of salmon, tilapia, cod, and shrimp
I. Introduction The problem While DNA profiles can be obtained from evidentiary swabs, forensic science is currently deficient in the methods to determine the tissue source of the DNA. While proper confirmatory tests exist for biological fluids such as semen1,2 and blood3, similar tests for the confirmatory identification of saliva are lacking. Being able to confidently identify the source material of the DNA may help criminal investigators corroborate the claims of an alleged victim or suspect
based tools are essential to the design of experiments in the post-genomic age. They allow scientists to manipulate the large datasets gained from genome sequencing efforts to identify potential research targets; analyse target sequences to predict protein characteristics; and to share annotated data through simple, on demand interfaces. This gives researchers more information to use when creating a hypothesis, which saves time and money that would have been spent of failed experiments. Informed use

Cereals, millets and legumes are generally pre-processed by fermentation, germination (malting), cooking, milling and roasting to enhance their functional and nutritional values. Germination/sprouting/malting is a biochemical process which involves transition of a seed from dormant state to vital active state. The prime objective of this traditional process is to promote the development of hydrolytic enzymes that are not active in raw seeds (Dewar et al., 1997). Malting is a complex process that
Sequence and structural proteomics involve the large scale analysis of protein structure. Comparison among the sequence and structure of the protein enable the identification on the function of newly discovered genes (Proteoconsult, n.d.). It consists of two parallel goals which one of the goals is to determine three-dimensional structures of proteins. Determine the structure of the protein help to modeled many other structures by using computational techniques (Christendat et al., 2000). This approach
Bioaffinity chromatography is a type of affinity chromatography in which biological compounds such as immunoglobulin-binding proteins, enzymes, lectins, carbohydrates, avidin/biotin system and antibodies are used as ligands (Hage, 2006). Immunoglobulin-binding proteins, namely protein A which is produced by Staphylococcus aureus and protein G which is produced by streptococci, are the ligands that are used in the vast majority of bioaffinity chromatographic applications (Tetala and van Beek, 2010)
cells, and there are five main methods by which substances can move across a cell membrane: Lipid Diffusion, Osmosis, Passive Transport, Active Transport, and Vesicles. Lipid Diffusion (or Simple Diffusion), a few substances can diffuse directly through the lipid bilayer part of the membrane. The only substances
Transketolase has a complete protein sequence length of 623 AA. Within the cell, specifically, TK is located in the nucleus and cytosol. Understanding transketolase’s function is quintessential. Its function is the “catalyzation of the transfer of a two-carbon ketol group from a ketose donor to an aldose acceptor, via a covalent intermediate with the cofactor thiamine pyrophosphate (Universal Protein Resource, Transketolase, 2002-2014).” The total length of the protein chain goes from amino acid #1
Studies continue to slowly progress, hoping to find methods to immunize against more prion diseases. Problem No one presently has a solid understanding as to why TSE, or prion diseases, occur. The simple explanation is that PrP(c), the normal isoform of the prion protein, is forced to fold into PrPSc, the other pathological isoform, causing the misfolded PrP(c) to acquire protease-resistance. As to a physical presentation, a clumped protein consisting primarily of alpha-helices (spirals) is converted
sure it stays on its correct course, even assisting in apoptosis. The TP53 gene sends signals to make a protein called tumor protein p53 (or p53). This protein is the tumor suppressor itself, it regulates cell division by keeping cells from proliferating too fast or uncontrollably. The p53 protein is located at the nucleus of all cells in the body, and it binds directly with DNA. Human protein p53 is a phosphoprotein; it has a very specific structure closely related to its function. The

These enzymes only need a low temperature of around 50ËšC, and this means a saving of energy, as less electricity is used by the appliance but the difficult stains are still removed. In the dairy industry, enzymes are used to remove lactose from milk as some people are allergic to lactose. The enzyme lactase is added ... ... middle of paper ... ... assay) are used in hospitals to diagnose certain diseases as specific proteins are detected in
therapeutic drugs in the future and furthermore, from the study it has been known that with the improvement of the technologies related to these fields many challenges like developing a precise medicine for prostate cancer and effective prediction of 3D protein structure can be addressed clearly. The information from the study clearly describes that bioinformatics, proteomics and genomics have great potentials currently as well as in the future if they are enhanced in the appropriate manner.
archaea (Martin W. 2005). Being the main hub for the inner workings of a cell involves different functions overall. These nucleic functions are determined by the genes within the DNA of the cell. Functions of the cell are also regulate by soluble proteins that come in and out of the cell via the membranes and specific channels or the nuclear pore complexes. The overall objectives of the nucleus include; gene expression, compartmentalization, and processing pre-mRNA. The functions of the organelles
cut the DNA into fragments and then run on gel electrophoresis for separation according to their lengths. As we know that a single strand of plant DNA or animal DNA contain tens of thousands of genes, each working for the production of a specific protein essential for the growth and survival of the organism. PCR (polymerase chain reaction) can also be used for the amplification of genes segments which can be isolated through same procedure as gel electrophoresis. Selectable markers are used for the
proximal hairpin loop requires the recruitment of proteins such at TAT and P-TEFb. Currently supporting, but oversimplified, models tell us that Tat bind to the hairpin loop created by the Tar sequence of the HIV LTR, which then recruits P-TEFb. Through the use of CDK9, p-TEFb then phosphorylates Ser2 of the CTD, and allow for elongation. Nevertheless, it has been found that another protein called TCERG1 is involved in Ser 2 phosphorylation. This protein, originally called CA150 (2), has been characterized
what this paper answers. PROCEDURES: When looking at the methods in this paper, it is easy to get lost and confused amidst all the scientific terms and complicated language. However, when broken down into simpler terms, the methods used in the experiment in the paper become much clearer and create a basis for understanding for the remainder of the paper. Following is a short and understandable explanation of the methods used in the paper and also an explanation of the experiment that
created by mutations in both copies of the cystic fibrosis transmembrane conductance regulator gene or the CFTR gene. This means a person must inherit the recessive gene from both parents to have cystic fibrosis. The CFTR gene codes for an ion channel protein that conducts chloride ions across the epithelial cell membranes of the passageways of the respiratory, digestive, and reproductive systems. Mutations of the transmembrane conductance regulator gene causes malfunctions of these chloride ion channels
genomics. Proteomic consists of protein sequence information and genomic consists of genome sequence information. It is used to annotate whole genome and protein coding genes. Proteomic data provides genome analysis by showing genome annotation and using of peptides that is gained from expressed proteins and it can be used to correct coding regions.Identities of protein coding regions in terms of function and sequence is more important than nucleotide sequences because protein coding genes have more function
