WitrynaThis thesis presents several studies, using genetics, cell biology techniques, transcriptomics and metabolomics, to investigate the function of cell division proteins. The protein WhiA is present in most Gram-positive bacteria, binds to DNA and induces expression of cell division genes.

Most cells undergo cell division via mitosis, thus producing 46 *2 = 92 chromosomes …
WitrynaThe reduction in chromosome number is achieved by the process of meiosis. In meiosis, there are usually two steps, Meiosis I and II. In Meiosis I homologous chromosomes segregate, while in Meiosis II sister chromatids segregate. Most multicellular organisms use meiosis to produce gametes, the cells that fuse to make … WitrynaMeiosis 2 is similar to mitosis because it separates the chromosomes to have sister chromatids in each cell. In both processes, you are separating the chromosome and …
