The engineering helps eliminate diseases such as cystic

The advance of genetic engineering provides
advantages to humans. As inheriting bad genes from parents result it many human
diseases, genetic engineering has the ability to reverse this issue by replacing
bad genes with the copy of healthy genes. With this capability, genetic
engineering helps eliminate diseases such as cystic fibrosis, Alzheimer’s or other
heart diseases. Genetic engineering also has the potential to extend human life
span. Scientists believe human life expectancy will increase to the range between
100-150 years. By changing the individual’s genome, such as avoiding telomeres
from shortening, the aging process slowdown, increasing human life span.
