Answer:
Cancer develops when the body's normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor. Some cancers, such as leukemia, do not form tumors.

A dominant trait can be described as a trait which is dominant over a recessive trait. A recessive trait can be described as a suppressed trait which gets masked by a dominant trait.
When the two alleles of a gene for a trait are similar, they are said to be homozygous. When the two alleles of a gene for a trait are different they are termed to be heterozygous.

Answer:
Both eukaryotes and prokaryotes have gene regulation strategies. By gene regulation, the amount of protein is maintained in the living cell.
In prokaryotes, operons are present which are controlled by a regulatory gene that regulates the synthesis of protein in prokaryotes. In eukaryotes, repressor and transcription activators regulate the expression of gene and protein formation.
So by gene regulation cell maintains the number of protein molecules to become too great for a cell. Without gene regulation the survival of any organism is not possible.
