Cell - cell division and growth: in unicellular organisms, cell division is the means of reproduction in multicellular organisms, it is the means of tissue growth and maintenance survival of the eukaryotes depends upon interactions between many cell types, and it is essential that a balanced distribution of types be maintained this is.

Meiosis (from greek μειώσεις, meiosis, which means lessening) / m aɪ ˈ oʊ s ɪ s / ( listen) is a specialized type of cell division that reduces the chromosome number by half, creating four haploid cells, each genetically distinct from the parent cell that gave rise to them this process occurs in all sexually reproducing single-celled and multicellular.

Chromatin plays a fundamental role in positive and negative gene regulation, because transcriptional activators and rna polymerase cannot physically access the dna regulatory elements when chromatin is in a compact form. Definition: a daughter chromosome is a chromosome that results from the separation of sister chromatids during cell division daughter chromosomes originate from a single stranded chromosome that replicates during the synthesis phase (s phase) of the cell cycle the duplicated chromosome becomes a. If the mitosis does not encounter any major obstacle along the way, the alleles in the daughter cell will be the same note that, for mammals, the original and daughter cells will be diploid, and therefore for a specific gene, there will be 2 alle.
