Consider the following statements regarding ‘Xenotransplantation’: ...
- Xenotransplantation involves the transplantation of nonhuman tissues or organs into human recipients. Hence, statement 1 is not correct.
- Genome editing (also called gene editing) is a group of technologies that give scientists the ability to change an organism's Deoxy-Ribonucleic Acid (DNA). In the recent heart transplant from pig to human, gene-editing was adopted to remove a sugar in its cells that’s responsible for that hyper-fast organ rejection. Hence, statement 2 is correct. One of the biggest obstacles to transplantation is organ rejection.
Consider the following statements regarding ‘Xenotransplantation’: ...
Explanation:
Xenotransplantation refers to the transplantation of tissues or organs from one species to another. In the context of the given statements, it specifically refers to the transplantation of organs or tissues from animals to humans.
Statement 1: It involves the transplantation of the tissues or organs of one human into another human.
This statement is incorrect. Xenotransplantation involves the transplantation of animal tissues or organs into humans, not the transplantation of human tissues or organs into other humans.
Statement 2: Gene editing is used in this process to reduce the likelihood of organ rejection.
This statement is correct. Gene editing techniques, such as CRISPR-Cas9, can be used to modify the genes in animal organs or tissues to make them more compatible with the human immune system. By editing specific genes involved in immune responses, scientists can reduce the likelihood of organ rejection when these organs are transplanted into humans.
Conclusion:
Only statement 2 is correct. Xenotransplantation involves the transplantation of animal tissues or organs into humans, and gene editing techniques can be used to decrease the chances of organ rejection. Therefore, the correct answer is option B - 2 only.
