describes or explains genetic mutations.
A) Mutation can disrupt normal cell activity and cause diseases, like cancer.
B) Mutations in parents' cells are then passed down to offspring via reproduction,
C) Our cells can recognise any potentially mutation-causing damage and repair it Eliminate
before it permanent.

Genetic engineering is important to the scientific community because A)
Genetic engineering provides crops that are less expensive to grow. One
of the biggest problems that the world may face in the near future is a
food supply shortage due to the increasing exponential growth of the
population. Genetic engineering provides crops that are more hearty,
larger and less expensive to grow that may be the answer to mounting
future problems. The ability to manipulate plants in the lab makes
altering their growth pattern a much faster change than many years of
natural selection in the farm and field.
