Oct 30, · ADULT BRAIN CELLS SAID TO REPRODUCE. By Holcomb B a team of American and Swedish scientists reported yesterday that they had discovered the generation of brain cells in adult humans for the. Stem cells are the cells that divide to make more cells, replenishing cells that normally die or are lost. Adult tissues, such as the skin and intestines, constantly lose cells on a daily basis.
Bacterial cells reproduce through a process called binary fission. During this process, bacterial cells reproduce by budding new genetically identical organisms from portions of their bodies. Asexual reproduction is a disadvantage to mitosis because it negates the positive effects of genetic variation and recombination. Most human cells are frequently reproduced and replaced during the life of an individual. However, the process varies with the kind of cell. Somatic, or body cells, such as those that make up skin, hair, and muscle, are duplicated by mitosis.
