Answer 1

The right answer is A option.

Hope it helps you.

Thanks you.

Answer 2

The Answer is
CRISPR - Cas9

FULL EXPLANATION .

The scientists used the groundbreaking gene-editing tool CRISPR-Cas9 to repair the DNA piece that causes a common genetic heart disease known as hypertrophic cardiomyopathy. This technique would prevent the disease from being inherited by succeeding generations.

The experiments on the embryos were conducted in the US following all ethical guidelines. IBS researchers provided CRISPR-Cas9 and analyzed the DNA of the embryos to make sure that the procedure worked correctly.

CRISPR-Cas9 combined with in vitro fertilization (IVF) and preimplantation genetic diagnosis (PGD) could be helpful for many other genetic diseases. However, the scientists stated that "genome editing approaches must be further optimized" before moving to clinical trials.

"We have succeeded in correcting the mutated gene which causes hypertrophic cardiomyopathy in human embryos with high efficiency and specificity," stresses Jin-Soo KIM, Director of the Center for Genome Engineering, within the Institute for Basic Science (IBS). "Research on human embryos has been a very sensitive subject. The application of this technology to clinical practice in the future requires not only additional research, but also social consensus...
