Results In Repair Of An Organism. Some single-celled organisms use a type of mitosis as their only form of reproduction. If tumour cells successfully invade other tissues in the body the result is cancer.
The goal of the repair process is to fill the gap that results from the tissue damage and restore the structural continuity of the injured tissue. Every living organism has DNA and every living organism engages in DNA replication the process by which DNA makes an exact copy of itself during cell division. Multicellular organisms have a hierarchical structural organization in which any one system is made up of numerous parts and is itself a component of the next level.
Cell division also called mitosis occurs in all living things.
In some organisms however notably the slime molds no regular pattern of growth occurs and a formless cytoplasmic mass is the result. Some single-celled organisms use a type of mitosis as their only form of reproduction. In some organisms however notably the slime molds no regular pattern of growth occurs and a formless cytoplasmic mass is the result. Through comparison of growth on the complete plate and lack of growth on media lacking specific nutrients specific loss-of-function mutants called auxotrophs can be identified.
