Vid30 complex participation in the degradation of CDC25 in yeast and their role in Ras/ cAMP/ PKA pathway

Background: Unicellular organisms such as Saccharomyces cerevisiae in its total life cycle is exposed to diverse and changing nutrient conditions. Thus, in order to survive and achieve a competitive advantage, it has adapted itself such that it not only uses the wide range of available nutrient sources but also the sources that are nutrient rich. It mainly uses fructose and glucose by rapidly fermenting to alcohol. In response to these nutrient conditions, the intracellular trafficking transcription and turnover of protein from nutrient transporters (e.g. Hxts) get regulated. Therefore, when the availability of the glucose increases, the expression of low- ...

Expressionism is referred as a modernist form of art that was initially introduced in Germany during the early part of the 20th century. The main feature of this art is to present a subjective perspective by altering its elements to stimulate emotional impact which eventually leads to conjuring certain moods and perception. There was the conviction that artists have the ability to express some form of inner awareness through their works of art, and this notion has been prevalent among artist and intellectuals in Germany in early twentieth century (Perry, 1993). In due course, the expressionist considered looking for ...

1. a. The pKa value of an amino acid is an indication of how strong or weak an amino acid is, based on the said acid’s dissociation constant. An amino acid that has a high pKa value is weaker than on that has a low pka value. Given that an acid’s dissociation constant is Ka, the pKa value is given by the formula: pKa = -log10Ka pH = pKa + log ([A-]/[HA]),It follows that for Cys12, 7.4= 7.2 + log([Cys-]/[HCys]) 7.4-7.2 = log([Cys-]/[HCys]) 0.2 = log([Cys-]/[HCys]) 100.2= Cys-/HCys Therefore, Cys-/HCys = 10-4Similarly, ...

Cephalexin and Gentamicin The mechanism of action of amoxicillin is focused on the prevention of the synthesis of the bacteria’s cell wall through the binding and inhibiting of the cell wall transpeptidases (Katzung, Masters, and Trevor, 2012). Specifically, it attaches to the penicillin-binding protein 1A found in the cell wall of bacteria. Then, the agent disintegrates the lactam ring to allow the acylation of the penicillin-sensitive transpeptidase C-terminal domain. The formation of the cross-link of the linear peptidoglycan strands is prevented by the inactivation of transpeptidases. Since the third and last stage ...

Part one

A cyborg manifesto is a brilliant article authored by Donna Haraway. It is solely aimed at criticizing the traditional notions of feminism, especially through putting greater emphasis on the issue of identity rather than affinity. In this article, Haraway uses the image or metaphor of a cyborg to urge feminists to move beyond the retrogressive limitations of traditional feminism, gender and politics. The idea of Haraway’s Cyborg calls for a non-essentialized and material-semiotic metaphor that is considered capable of uniting diffuse political coalitions through the notion of affinity (Haraway, 1991, p.153). She clearly addresses the rift between a feminist discourse ...

Background

Early scientists and nutritionists believed that the most vital nutrient in living organisms, for building and maintaining the body was the protein. The role of proteins as enzymes came into existence several years later. This was around 1926 when experiments showed that enzymes were proteins. Insulin was the first protein to be sequenced. Hemoglobin was the first structure of proteins to be resolved. Myoglobin was then resolved later.

X-ray diffraction analysis (X-ray crystallography) led to the determination of the structure of the proteins (three-dimensional structure). The purification of proteins can be made possible from cellular compounds. Several methods have ...

Cultures of Walt and Hmong people are almost entirely different. Walt’s culture is chiefly formed and influenced by his military past as a Vietnam War veteran. Throughout the movie Walt repeatedly demonstrates strong signs of racial bias, especially towards the Asian people he used to fight against during the war. For instance, Walt constantly mispronounces names and words, most likely on purpose, including “Humong” instead of Hmong, “Yum Yum” rather than Youa, and so on. Also, he holds certain racial stereotypes; for example, that Asian people can only excel at math. As Sue puts it, Walt is a very “old-school” American ...

DNA DAMAGE

1. Introduction The p53 gene is a tumor suppressor gene that is activated whenever a cell is subjected to cell damage. The p53 gene determines whether a cell should survive a damage or should undergo apoptosis. These decisions are regulated by posttranslational modifications. Phosphorylation of the serine 46 residue is one such modification that is relevant to this study. However, it is unclear why a Ser46 phosphorylated p53 favors apoptosis over survival (Feng et al. 2006, p. 2812; Taira et al. 2014, p. 717). Studies have shown that the elusive molecular mechanism of Ser46 phosphorylation of p53 induce apoptosis in the tumor ...
