Protein Synthesis The Expression of a Gene nbsp;nbsp;nbsp;nbsp;nbsp;The process of Protein Synthesis involves many parts of the cell. Unlike other similar productions, this process is very complex and precise and therefore must be done in proper sequence to work effectively. The slightest error during this process could cause the action to experience difficulty or even fail. For example, in the production of starch, glucose molecules are combined to be stored and eventually utilized as usable chemical energy. The cell can break down the starch with little difficulty as if each molecule was identical, even though there is a wide variety of molecules. This is a different case in Protein Synthesis. In Protein Synthesis, there are†¦show more content†¦1). The nitrogenous bases are held together with weak hydrogen bonds. One polynitrogenous chain runs in a 3-5 direction, the 3 being the top hydroxyl and the 5 being the bottom phosphate attached to the carbon five of the sugar. The other string runs the opposite. The two s trands of the structure cannot be identical but they are complimentary. There is no restrictions on the placement and sequence of the nucleotides, which becomes important in storage of information. nbsp;nbsp;nbsp;nbsp;nbsp; TRANSCRIPTION: The Synthesis of RNA nbsp;nbsp;nbsp;nbsp;nbsp;Genetic information would be rendered useless if the stored information did not have a way of reaching the desired focal area. Since protein synthesis occurs in the cytoplasm and the DNA must remain in the nucleus, a way of transporting the code is essential. This comes in the form of messenger ribonucleic acid or m-RNA. Since the information on the DNA must stay the same on the m-RNA, the two have to be very similar. There are three major differences between RNA and DNA. RNA is only a single strand. The five carbon sugar of RNA is ribose opposed to deoxyribose and in RNA the pyrimidine uracil (U) replaces DNAs pyrimidine thymine (T). Since RNA is produced from DNA, the nucleotides of RNA can hold the same information as the nucleotides of DNA because the code for amino acids is centered around the RNA structure. nbsp;nbsp;nbsp;nbsp;nbsp;TheShow MoreRelatedGene Expression in Eukaryotes696 Words   |  3 Pageswork with them. This is where mRNA will come into play. The mRNA will provide the workers or cells with new instructions that will be used to build the protiens. In transcription DNA is unzipped and the enzyme RNA polymerase RNA polymerase binds to the promoter region. This starts the unwinding of the DNA strands, and the polymerase starts RNA synthesis which runs along the template strand of the DNA. In eukaryotic cells proteins called transcription factors bind to promoters that include a TATA boxRead MoreDifferences Between Science And Pseudoscience1526 Words   |  7 Pagesitself and held together by disulfide bridges and hydrogen bonds.

Based on the FL-NO fluorescence, it was determined that the potato produced high levels of NO in the root apical zone. The plant was treated with 250 micromoles of AlCl3 for 48 hours. This significantly diminished the NO synthesis in the elongation and the differentiation zones in the potato. These zones are where the plants cells are created and how the plant grows.

Gene Product/Role The FAS gene is responsible for the origination of the FAS protein synthesis. The FAS protein is a transmembrane receptor that, when bound to FASL induces a trimerization of the FAS protiens and a conformational change ensues in its’ cytoplasmic domain. The structural change results in the recruitment of the death domain containing adapter molecule tumor necrosis factor receptorRead MoreProtein And The Amino Acids Essay974 Words   |  4 Pagesintestinal cells split most of the tripeptides and dipeptides into single atoms (book). After digestion, protein absorption occurs, through specific carriers that transport amino acids into the intestinal wall. Here,the amino acids are used either for synthesis of needed compounds or for energy. Unused amino acids are transported to surrounding fluid where they enter capillaries on their way to the liver (book). Protein plays critical roles in the human body.
