Breeding crops with higher levels of vitamins and minerals or higher proteins and healthier fats is called:

In gene therapy of adenosine deaminase (ADA) deficiency, the patient requires a periodic infusion of genetically engineered lymphocytes because:

Statements related to human Insulin are given below: Which statement(s) is/are correct about genetically engineered insulin?

(a) Pro-hormone insulin contains an extra stretch of C-peptide.

(b) A-peptide and B-peptide chains of insulin were produced separately in E. coli, extracted, and combined by creating disulphide bond between them.

(c) Insulin used for treating diabetes was extracted from cattle and pigs.

(d) Pro-hormone insulin needs to be processed for converting into a mature and functional hormone.

(e) Some patients develop allergic reactions to foreign insulin.

Choose the most appropriate answer from the options given below.

When gene targeting involving gene amplification is attempted in an individual's tissue to treat disease, it is known as:

Now a days it is possible to detect the mutated gene causing cancer by allowing radioactive probe to hybridise its complimentary DNA in a clone of cells, followed by its detection using autoradiography because:

With regard to insulin choose correct options.

(a) C-peptide is not present in mature insulin.

(b) The insulin produced by rDNA technology has C-peptide.

(c) The pro-insulin has C-peptide.

(d) A-peptide and B-peptide of insulin are interconnected by disulphide bridges.

For effective treatment of the disease, early diagnosis and understanding its pathophysiology is very important. Which of the following molecular diagnostic techniques is very useful for early detection?

The Adenosine deaminase deficiency results into:
