Question

7. In recent years, DNA sequencing has become an important tool in biomedical science. What is the use of knowing the DNA sequence of genes from an individual?

_ can provide information about risk of developing specific diseases in the future.

_ identifies proteins that are misregulated during disease

_ influences treatment plans for certain drugs.

_ provides a complete understanding of disease mechanisms.

Answer 1

DNA sequencing is defined as the determining the whole sequence of DNA by means of certain technique such as sanger method.

By means of DNA sequencing, we can found that whether a person having that gene will show disease in future or not. This technique is used to identify the certain mutation in the specific gene. For example detecting the mutation for abnormal haemoglobin gene in foetus via taking sample from chorionic villus. This will helps in curing the disease so that in future such individual will not have disease.

That's why right option are:

'can provide information about risk of developing specific diseases in the future.'

influence treatment plan for certain drugs.
