At present, scientists can determine the arrangements or relative position of genes of DNA sequences on a chromosome. how does this knowledge benefit us?
- It is possible to know the pedigree of livestock.
- It is possible to understand the causes of all human diseases.
- It is possible to develop disease resistant animal breeds.
Which of the statements given above is/ are correct?
-
1 and 2 only
-
2 only
-
1 and 3 only
-
1, 2 and 3
D
Correct answer
Explanation
Significances of genome sequencing:
It is possible to know the pedigree of livestock, to develop disease-resistant animal breeds, to understand the causes of all human diseases, to do newborn genetic screening.
This will enable the rapidly emerging medical fields of Predictive Medicine and Personalized Medicine and will mark a significant leap forward for the clinical genetic revolution. Full genome sequencing is clearly of great importance for research into the basis of genetic disease.
