The fact that diatoms a urea cycle originally believed originally believed to exist only in multicellular organisms may have to explain their success in colonizing the oceans. In addition, the diatom cell nucleus contains genes that migrated with the genome of diatom chloroplasts and bacteria.. Diatoms are the major component of phytoplankton and thus form the basis of the marine food chain. With cells with their photosynthesis chloroplasts, they are making a significant contribution to the production of oxygen in the atmosphere.
The number of metabolic paths branching off from the urea cycle in diatoms is particularly high. For example, arginine and ornithine, the intermediates of the urea synthesis, used in the development of the components of the cell wall. Diatoms obtained the enzymes. For this by lateral gene transfer from bacteria The reason for the superiority of diatoms over other single-celled organisms in the oceans is the good networking between the various metabolic pathways.The ambassador program to speak for young women and church groups the breast self exams and breast cancer awareness.
