Answer 1

Mutuations are the abnormal changes in the DNA of the gene. Building block of the DNA is known as bases and mutuation is also seen in this bases making the changes in whole sequence and that show the change in cell division and size. And even a mutuation in single base can result into a major effect in DNA and cell.

Mutuation can cause the stoppage of the protein in gene also and can also make extra protein in gene and can also be a reson of certain diseases . One of which is sickle cell anemia.

Cell becomes very large sometimes due to this mutation can has a great effect on cell division it controls the cell division sometimes it is seen in cell or required in cell to prevent cancer and called tumor suppressor gene and somtime it causes cancer or becomes a reason of cancer called oncogene.

Mutation in cell cycle occurs in two stage one is called inherited which is seen in the egg cells sperm cells during the formation of the zygote while one is acquired which is seen after the birth.

Mutuation is of various types which alters the arramgements of base pair in DNA of the gene it is done by sometimes substitution of base pair , insertion and deletion

It causes changes in the cell cycle division sometimes size gets increased and altered.

Mutation in the gene causes the uncontrolled and fast division in the cell cycle creating the cancerous elements cell which promotes the cell division called proto oncogene is positive promoter and normal gene but when it gets mutated converted into oncogenes which causes uncontrolled cell growth and causes cancer.
