In evolutionary biology, phylogenetic trees are used to exhibit and illustrate the evolutionary relationships of two or more organisms, and identify the origins of life altogether. To achieve this, there are three methods of classification which are phonetics, cladistics, and taxonomic groups.
Answer:
The correct answer is - Mutation in particular DNA segments can lead to the loss of apoptotic control which allows the cancerous or damaged cells to survive longer.
Explanation:
An error or change in a DNA segment or DNA repair gene mistakes become mutations if not corrected. These mutations may lead to change in the function of the specific functions that may lead to cancer. Such mutations are tumor suppressor genes or oncogenes. The activities of genes regulate the signal when they detect damaged cells and such cells should undergo apoptosis (programmed cell death).
The loss of apoptotic control by a mutation in such genes allows cancer cells to not follow apoptosis and leads to survival for a longer time and allow them to divide, accumulate and proliferate.
