Answer:
Over our lifetime, our DNA can undergo changes or mutations that result in differences in the DNA sequence and may affect the proteins that are made. Mutations can occur as a natural consequence of errors in DNA replication or as a result of exposure to environmental factors such as smoking, sunlight or radiation.
Explanation:
<span>The mechanism of descent with modification is known as "evolution". This idea of descendants of adult species being similar in most ways to their ancestors but slightly modified in some way is the basis of an entire belief system for some. For example it is not unreasonable to believe over time and generations, humans may develop an extra or altered digit on the hand to accommodate cell phone usage.</span>
Any mutations in DNA are forever, since DNA is the master blueprint. All mutations will be passed onto new cells through DNA replication, and all RNA made from that DNA will also have the mutation. If the mutation occurs in sperm or egg cells, those mutations will also be passed on to the organism's offspring.
The purpose of genetic modification is to benefit human kind, regardless of disadvantages or environmental effects.
