Transmembrane protein

Introduction: Forensics is involved with the field of law. It involves the collection, preservation, and analysis of evidence found at a crime scene that is needed to be investigated for further information to be obtained. For the science involved in forensics is in the DNA left behind by suspects or victims. The DNA could be found in different forms such as fingerprints, cells such as blood, skin or hair. DNA is deoxyribonucleic acid, a self-replicating material, with the use of enzymes for…

involved a type of protein and that the water would have to pass by it could maintain continuous pressure . His research began around the 1980s when he studied membrane proteins from red blood cells and discovered them in the kidneys as well. When I analyzed the two peptides and the corresponding sequence, I realized that this was the protein many others wanted to know, and the cellular water channel. Agar agreed to his theory by conducting a test where he compared cells that were proteins…

Meiosis starts: DNA Replicates I am going to draw a nucleus with DNA inside it represented with beads as the four pairs of chromosomes. Outside of the nucleus there will be centrioles drawn. This is where meiosis begins and replicates the cell Spindle fibers start to form on the centrioles and chromosome pairs bind together making tetrads. Nuclear membrane starts to dissolve. Nuclear membrane will be drawn in dashed lines. The chromosomes will be homologous pairs with centromere in the center…

subcortical infarcts and leukoencephalopathy (CADASIL) is the metabolic condition caused by a production of abnormal Notch 3 receptor proteins. The result of these abnormal proteins causes thickening of blood vessel walls that block the flow of blood to the brain. This is caused by a mutation in the Notch 3 gene. Cells containing abnormal Notch 3 receptor proteins results in disrupted normal functionality and ultimately leads to apoptosis of these cells. As the name of CADASIL suggests, it is an…

The folding mechanism of knotted/slipknotted protein has become a challenging question over the last two decades.(10, 89, 90, 95, 99, 100, 173-175) Understanding how those proteins fold would be a great proceeding of the field of protein folding. Recent advances on protein folding shed light on this question using both experimental and computational methods. .(10, 89, 90, 95, 99, 100, 173-175) Most experimental studies on the folding of knotted protein have been limited to bulk experiments.(84,…

In Procedure 6.1, two different gels were used. One gel was 2.0% agarose while the other gel was 0.8% agarose. The reason we poured two gels was because each gel had a different purpose. The 2.0% agarose (thicker gel) was used to determine amplicons while the 0.8% agarose (thinner gel) was used for restriction fragments. One gel was ‘thicker’ than the other gel to distinguish smaller segments than the thinner gel. By having a thicker gel, smaller segments can move better and not be cleared out…

especially calcium, could interfere with the strand interactions and care is taken to avoid inclusion in its production. Kevlar's structure consists of relatively rigid molecules which tend to form mostly planar sheet-like structures rather like silk protein.…

phospholipids, cholesterol, proteins, and carbohydrates. The phospholipids and cholesterol both help create the roof of the cell membrane and they both regulate the fluidity of the cell membrane. The proteins in the cell membrane help provide a structural function, transport function, and signaling function all within the membrane (Yeagle, 1989). The carbohydrates are on the external side of the cell membrane. Also the carbohydrates provide a signaling function with the proteins and lipids. B.…

Caenorhabditis elegans C. elegans is a nematode worm that considers as one of the simplest multicellular model organism. It is a free-living soil animal that feeds on microbes in decaying plant environments while in vitro, it mainly feeds on bacterial lawn (40). Sydney Brenner has proposed C. elegans as an experimental model organism and it has been used in biological fields, it played a huge role in the understanding and development in the knowledge about multicellular organisms since 1960s (8)…

central dogma is the explanation of how genetic information flows as it is passed from DNA to RNA to protein. DNA replicates and converts the information it carries into RNA, this process is called transcription. During transcription the information is passed through nucleic acids and there is no need for a change in the “language.” When RNA continues the flow of information and it is passed to proteins, this is called translation. It is called translation because the information must be…
