Please insert your professor’s name here Please insert course number here Introduction Kinesins are proteins which serve as molecular motors for the directional transport of various cargos (Hirokawa et al. 10: 682-696). They perform this important function using different mechanisms to recognize, bind, determine the direction of transport and unload the cargos with an energy efficiency which can exceed 50%, thereby equipping them to play important roles intracellularly in the transport of organelles and vesicles, in biosensing as well as in the development of other bioengineering solutions (Agarwal 11; Hirokawa and Takemura 301: 50–9; Hirokawa et al. ...

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- ...

Analysis of the Trapping Potential of the Linear Radio

Frequency Ion Traps for Quantum Computing

The dynamics of an ion in a linear radio frequency ion trap is established by classical motion equation. For an radio frequency electric potential,

The x and y equations become Mathieu equations;

d2x / dℓ2 + (a – 2qcos (2ℓ)) x = 0 (2) and, d2y/dℓ2 – (a – 2qcos (2ℓ)) x = 0 (3)

where, ℓ = Ωt/2, is time which is dimensionless, a = (4QV)/mr20Ω2 and q = (2QV)/mr20Ω2 are DC and RF dimensionless. Q and m are ion and mass. In the assumptions regarding psuedopotential, q <<1, the motion of ion along the i axis ...
