Inherited Diseases - Cystic fibrosis

Question 1

A recessive gene is responsible for Cystic Fibrosis. You must inherit 2 recessive genes to become a sufferer of Cystic Fibrosis. Two parents that carry the gene can produce offspring that suffer from it.

Question 4

Genotype of Cystic Fibrosis - CC

Answer 4

Question 5

Genotype of Cystic Fibrosis - Cc

Answer 5

Parent that carries one recessive gene-carrier

Question 6

Genotype of Cystic Fibrosis - cc

Answer 6

Someone that suffers from cystic fibrosis

Question 7

Gene therapy for Cystic Fibrosis

Answer 7

• potential treatment for cystic fibrosis
• involved inhaling into the lungs the correct gene for mucus production
• gene will enter the cells of the respiratory system, code for the correct proteins and provide temporary relief from symptoms

Question 8

Negative aspects in relation to gene therapy

Answer 8

• Re-administer
• Temporary
• Only treats cells in the respiratory lining
• Can still pass on cystic fibrosis

Question 9

Positives

Answer 9

• Non invasive
• Gives relief
• Easy to administer
