Q. Consider the following statements:
1.Gene editing can be used to eliminate genetic differences.
2.Casgevy is a revolutionary gene-editing therapy designed to treat sickle cell anaemia..
Which of the statements given above is/are correct?
Answer: B
Notes:
Explanation-
Statement 1 is incorrect. Gene editing is a tool that can be used to modify specific genes in an organism, but it cannot eliminate genetic differences. Every individual has a unique genetic makeup, including variations in their DNA sequence that are responsible for many of the differences between individuals.
Statement 2 is correct. Casgevy is a revolutionary gene-editing therapy designed to treat sickle cell anaemia. It utilizes the advanced CRISPR-Cas 9 tool for editing genes. It works by editing the patient’s genes to revive fetal haemoglobin, which is normally switched off after birth. This compensates for the defective haemoglobin in sickle cells, reducing the disease’s severe symptoms and complications.
