Cell division is the most important phenomenon for reproduction and the continuity of the life. Each of the stages of the cell division (G1, G2, M, S) affects all the process and the importance of this process’s control is of vital importance. Checkpoints regulated by proteins and different transcription factors are responsible for this process. The identification of any regulatory factor of the cell divison cycle is of great significance for achieving a deeper understand of the cell cycle, errors in the cell cycle (cancer mechanism) and complex processes, such as aging, senescence etc. Our research group aimed the identification of the subunits of Mb304 which are involved in the cell growth/size regulation. Previous studies have shown that two of the subunits, reciprocally Mb304-a and Mb304-b of Mb304 complex are directly involved in the regulation of the checkpoint G1/S and in the editing of DNA errors.

The electron excitation in the antenna (which varies between organisms) of the photosynthetic organisms enables the light absorption. The antenna of the bacteria can be in the form of the ring, while the chlorophyll pigments acts as antenna in the plants and higher organisms and its function is the absorption of the photons.

Prokaryotic mRNA is most of the times polycistronic, while the eukaryotic mRNA is monocistronic. The 5′-7 methyl guanosine is absent in prokaryotes, while in eukaryotes is present.

Albania is one of the oldest countries of the Balkan Peninsula. The most distinctive features of Albania are the nature virginity and the hospitality of the people. below are some of the pictures taken by my friends Doina Jano and Malvina Shtembari in my home country.

Table 1. Enzyme assay reaction were prepared according below table. After adding 0,1%SDS mixture were vortex at 28℃ for 5 minutes. Incubation of tubes occurs at 28℃ for 15 minutes. After adding 1M Na2CO3 mixture was vortex. After all reaction mixture were centrifuged and debris was discarded. Remaining part taken as 200 μl was added into well plate from F1 to F7 with respectively. Spectrophotometric measurements were applied at 420 nm.

Table 1. Substrate preparation were done by applying indicated amounts of ONPG by simple dilution. Stock solution of ONPG was 15mg/ml.Then, reaction mixture were prepared by adding Z buffer, Chloroform, 0.1 % SDS by respective manner. Na2CO3 was added to end the reaction.Each tube contained 800 μl cell lysate.
