Most of us has normally-functioning tissue and organs even if the cell has multiple mutations because of DNA repair mechanism.This repair mechanism has multiple processes by which any damage in the genetic material can be repaired before the protein is synthesized.In human beings there are many factors like environmental factors and metabolic activities that can cause mutation in DNA but the repair system does not allows the abnormal DNA to form abnormal proteins this saves the abnormal functioning of tissues and organs .More than 1 million molecular lesions per cell are repaired, these lesions leads to structural damage and the damaged cells are killed by apoptosis. This repair system continues as the cells divide and any alteration in the DNA is solved prior to the protein synthesis this result sin normal functioning of tissues and organs.
Answer:
Colchicine
Explanation:
Colchicine is an alkaloid derived from the autumn crocus (Colchicum autumnale).
The effect of colchicine, which inhibits microtubule polymerization and thus assembly of the mitotic spindle, demonstrates the presence of another checkpoint in the cell cycle. When colchicine is added to cultured cells, the cells enter mitosis and arrest with condensed chromosomes. With increasing time, a large fraction of the cells in a culture become arrested, thus permitting determination of the size, shape, and number of mitotic chromosomes — that is, the karyotype — in multiple cells. A checkpoint control somehow senses when the mitotic spindle has not assembled properly and prevents activation of the APC polyubiquitination system that normally leads to degradation of the anaphase inhibitor, required for onset of anaphase, and later to the degradation of mitotic cyclins, required for the exit from mitosis. As a result, MPF activity remains high, chromosomes remain condensed, and the nuclear envelope does not re-form.
Neanderthals is the closest relative to modern human. According to the study of evolution of man, neanderthals are the one with the closes facial structure and body structures to human.
Their higher classification is already considered as human.
The answer is <span>They decrease</span>
