burden‚ for example 50% of deafness is due to genetics as well as 40-50% of miscarriages. Another disease that is generally caused by genetics is cystic fibrosis which is caused by a defective gene. As many as four people in the UK have this gene; however the gene is recessive meaning children will only get the gene if both parents are carriers. (Cystic fibrosis results in a sticky mucus forming in the lungs‚ pancreas and intestines‚ and in the past it meant a low life expectancy but today a lot can be

Most of us‚ don’t think there are many cures for a lot of diseases and types of medical treatment we didn’t think was possible basically that is what gene therapy is in a nut shell; with its potential to eliminate or prevent diseases such as cystic fibrosis and hemophilia. It could even find a cure for AIDS‚ cancer‚ and heart disease. Gene therapy could be a medical life saver. What is Gene therapy for disease? Genes are what make you ‚ you.

Genetic Engineering useful or Harmful There are many issues which are associated with genetic engineering such as Cystic Fibrosis etc. Genes now days are being used in many ways for example they are now putting them in Plants to prevent them being destroyed by animals. It is very useful such as if there is a disease in a family and you want to prevent it to spreading the only way to do that is genetic engineering they can modify your genes and stop that disease to occur in your baby.

Rickets are mostly found in young children “…and 1 in every 100 non-Caucasian…” (Vitamin D Council 13). Rickets is a disease where one or one’s child has a severe vitamin D deficiency‚ it can also form softening and the weakening of the bones. Rickets are caused when a child is “…not getting enough calcium or lack of calcium and vitamin D…” (Mayo Clinic 4). Children that do not get enough sunlight or do not eat certain foods can start to develop a deficiency this is because the skin produces vitamin

Antibiotic resistance results from bacteria changing in ways that make those antibiotics no longer useful. Resistance is a common yet problematic issue in treating pulmonary exacerbations or infections in people with Cystic Fibrosis (CF). Not all bacteria are bad. However‚ there are some that can cause infections. As bacteria are exposed to antibiotics over time‚ resistance may develop‚ and the number of antibiotics we have to kill the bacteria decreases as well. Thus‚ it is important to learn
