DNA controls the cell when the DNA
in a gene is changed. The change can cause the cell to behave differently.
Some mutations happen as a mistake
spontaneously by a factor of the environment called a mutagen that has
radiation, chemicals, and high temperatures. Asbestos was a used chemical by
humans and many died because of it.They interact with the DNA molecule and
cause changes.
Some mutations are bad but some can
be good a lot of times such as the American Wirehair cat which the mutation had
no harmful effect.
Are mutations sometimes good for
people and animals?
What I find
most interesting is that the Wirehair cat mutation happened and that it had no
harmful effect on it.
1.)
Mutations can be sometimes caused by errors,
transcription, cell division, or external agents.
2.)
The cells grow and divide very quickly to make cancer.
3.)
Chromosomal mutations are common in plants.
