Question

Which of the following situations indicate a need for the process of mitotic cell division to occur? Check All That Apply Working as a physician in a hospital you take a piece of unbumed skin from a bur patient's body and apply it to the location of the burn so that new skin can grow in the region of the damaged tissue. You take one of your cells and sneak into the laboratory to create a twin for yourself so that you only have to attend half of the days at school After a nuclear plant meltdown, the local cattle are exposed to high levels of radiation, which causes the bulls to produce sperm with genetic abnormalities You have an infection, and as a result, the number of white blood cells increases in your body to fight off the disease

Answer 1

Ans) option A and B.

Grafts placed on recipients undergo mitosis in epidermal grafts.

Option B) is actually cloning. Mitosis or equational division occurs during cloning. To create a twin the cells need to be identical. Division by mitosis would hlep in creating tissues from a cell without much genetic variation. So one parent cell will split to form 2 daughter cell and each daughter cell will form two other daughter cells, thus increasing in number. Meosis would create haploid cells with genetic variations.

Option c.)Sperms are gametes and gametes are haploid as they undergo Meosis and carry only one set of chromosomes from the Father.

D) leukocytes are well differentiated in blood into neutrophils, lymphocytes, monocyte, eosinophils and basophils and do not undergo further division. Well differentiate cells do not undergo division.
