Choice A. This answer is incorrect. Initiation is a stage in translations that requires energy. During the initiation stage, a mRNA, a tRNA carrying the first amino acid of a polypeptide chain, and a ribosome’s two subunits are brought together. A small ribosome subunit is binded to mRNA and a tRNA initiation. The initiation complex is completed with the appearance of a large ribosome subunit. Initiation factors are proteins that are needed to combine each of the translation components together. The energy required for this comes from the hydrolysis of GTP (Reece, et al. 348).
Choice B. This answer is incorre...

... To enforce cell cycle arrest in Caulobacter crescentus, nutrient was limited by limiting the accumulation of DnaA. DnaA is a replication initiator protein that is degraded when low in nutrient availability. However, it was found that limiting nutrients did not change its rate of degradation. Rather, it downregulates DnaA translation instead (Leslie, et al. 1). The results show that regulating translation can provide for a way to control the concentration of important regulatory proteins as a reaction to environmental resources.
Vincent brings up a similar study about how translation is important and its effect on living organisms by analyzing bacteria. Inhibiting translation of E. coli with the use of antibiotics shows that the bacteria cannot thrive. This can benefit humans by finding a way to prevent bacterial infections by looking into different factors to do so.

- Protein synthesis 1. Introduction The information provided by DNA is in the form of a specific sequences of nucleotides along the DNA strands. The content in DNA is inherited by an organism is lead to specific traits because DNA dictates the synthesis of proteins and RNA molecules involved in protein synthesis. Proteins have a direct link with gene expressions through the stages of transcription and translation as DNA directs protein synthesis as it goes from DNA to RNA to proteins. 2. Genes specify proteins via transcription and translation • History, Beadle’s and Tantum’s study The relationship between genes and proteins was discovered beginning with a British physician in 1902 named Arc...

- Telomerase is the enzyme that maintains and prevents shortening of the protective telomeres at the ends of chromosomes. Without it, cells eventually enter replicative senescence (cell cycle arrest) as a result of telomere shortening from a lifetime of cell divisions. Due to the high expression of telomerase in invasive cancers, it makes for an attractive target for cancer therapy. In the quest for safer and more effective cancer therapies, researchers have explored many methods of targeting telomerase in cancer cells as a way to induce senescence or apoptosis (cellular death) including direct inhibition of telomerase, telomere disruption, telomerase-specific immunotherapy, and telomerase-sp...

Biology: Echinacea Extracts can Increase Gene Expression and Protein Expression of apoA-I in Human Intestinal Cells
- In this study, human intestinal cells (Caco-2 cells) were incubated without or with 100µl /ml Echinacea extracts for 5 hours, after which total RNA was extracted and assayed using reverse transcription-PCR. The results from reverse transcript-PCR suggest that Echinacea extracts are capable of up-regulating the level of ApoA-I gene expression. Caco-2 cells incubated with Echinacea extracts exhibited approximately a 17-fold increase in the level of gene expression as compared to Caco-2 cells without Echinacea extracts (Figure 1)....

- Distinct characteristics are not only an end result of the DNA sequence but also of the cell’s internal system of expression orchestrated by different proteins and RNAs present at a given time. DNA encodes for many possible characteristics, but different types of RNA aided by specialized proteins sometimes with external signals express the needed genes. Control of gene expression is of vital importance for an eukaryote’s survival such as the ability of switching genes on/off in accordance with the changes in the environment (Campbell and Reece, 2008)....

- Herein, we demonstrate that GMP polymer showed a little cytotoxicity and enhanced transfection efficiency, cellular uptake and maintained the phenotypic expression of human AD-MSCs. The results suggest that GMP polymer has excellent potential to be used in in vivo gene delivery. 3. Results and Discussion 3.1 Synthesis of GMP polymer Very recently, Lee et al. reported that glycol chitosan-methyl acrylate-polyethylenimine (GMP) polymer showed potential for gene carrier to cell types such cancer cells ....

- Because of their diversity in design, biocompatibility and biodegradability, peptide-based carriers have drawn considerable attention among various gene delivery systems. They have been used to deliver synthetic small drugs, nucleic acids (NA), therapeutic peptides and proteins. Different classes of peptides including protein-derived cell penetrating peptides (CPPs), cell targeting peptides (CTP), cationic peptides, designed amphiphilic peptides, and fusogenic peptides have been incorporated in delivery systems....

- Protein Synthesis The Expression of a Gene 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.... [tags: essays research papers]

- The comparison between BCSC and depleted control is of significant importance to understanding how to develop treatments for BCSCs. Out of 101,289 transcripts identified from single replicate differential expression analysis, 20 transcripts were found to be significantly expressed in either population. Two transcripts for histone cluster 1 and 2, HIST1H2BK and HIST2H2BE respectively, were shown to be downregulated in BCSC poputions. HIST1H2BK has previously shown to be overexpresed in micrometastasis, which are cells that maintain a very low population at a distant sight in ER-positive breast cancers....

- ... In HCMV there are three phases of gene expression sequence which are immediate early (IE), early (E), and late (L). The IE phase is short and its products are derived from three major genes which are IE1, IE2, and IE3 (Keil et al., 1987). The expression of both E and L genes need the prior expression of one or more IE gene products which function as transcriptional activators (Messerle et al., 1992). Generally the IE genes are responsible for regulating the production of host cell products, the E genes control the production of daughter virions, and the L genes are involved in the synthesis of proteins that form the structural components of the virion (Griffiths & Grundy, 1987)....

- PrfA is a transcriptional activator protein of facultative bacterium, Listeria monocytogenes. This microbe is an opportunistic intracellular pathogen mainly responsible for human foodborne infections worldwide.1 The pathogen especially causes Listerosis in humans upon invasion and is found in wild and domestic animals, water and soil.2 PrfA, is a27 kDa DNA binding protein and belongs to Crp/Fnr family of transcriptional activators.3 It is very specific in recognizing PrfA-dependent promoters that contain a 14-bp palindrome ,PrfA box.4 The PrfA protein is homologous to Escherichia coli cyclic AMP (cAMP) receptor protein (Crp) in structure and function.5 PrfA gene is considered as the main con...
