Answer:
B. Two cells, each containing the same number of chromosomes as the original cell
Explanation:
Mitosis is the type of cell division that results in the formation of two daughter cells with the same number of chromosomes as the progenitor cell. It occurs in somatic cells, whether diploid or haploid. It is the cell division that consists of 2 daughter cells being obtained from a cell, with the same number of chromosomes and genetically identical to the stem cell. The division of the cytoplasm is called cytokinesis, and the division of the nucleus, karyokinesis. Some cells do not perform mitosis and remain in interphase, but others frequently perform it (embryonic cells, cells of growth zones, tissue cells subject to wear).
It occurs in somatic cells. It consists of a single cell division (with four phases) and cell changes occur with movements in the chromosomes. At the end of mitosis cytokinesis occurs and two new cells are formed with the same chromosomal endowment as the original cell and the same genetic information.
Each mitosis is preceded by an interface, where duplication of the genetic material occurs, whose molecular basis is found in the replication of the DNA molecules. It acts as a mechanism that ensures that each daughter cell receives the same genetic information.
