Question

Consider the following statements:
I. Genetic changes can be introduced in the cells that produce eggs or sperms of a prospective parent.
II. A person’s genome can be edited before birth at the early embryonic stage.
III. Human induced pluripotent stem cells can be injected into the embryo of a pig.
Which of the statement(s) given above is/are correct?

• A. Only I
• B. Only II and III
• C. Only II
• D. I, II and III

Hint:

When dealing with genetic engineering and biotechnology, stay updated on the latest research technologies such as CRISPR, iPSCs, and gene editing techniques that allow for modifications in both somatic and germline cells.

Answer 1

The Correct Option is D

Step 1: Analyzing Statement I
Statement I says that genetic changes can be introduced in the cells that produce eggs or sperms of a prospective parent.
This is true. It refers to germline editing, which involves modifying the DNA in germ cells (eggs and sperms) to pass on genetic changes to future generations. Technologies like CRISPR-Cas9 allow for such modifications. Step 2: Analyzing Statement II
Statement II states that a person’s genome can be edited before birth at the early embryonic stage.
This is true. Genome editing technologies, such as CRISPR, can be used to edit the genome of an embryo at the early stages of development. This allows for the potential correction of genetic disorders before birth.
Step 3: Analyzing Statement III
Statement III states that human induced pluripotent stem cells can be injected into the embryo of a pig.
This is true. Induced pluripotent stem cells (iPSCs) can be generated from human cells and injected into the embryos of other animals, including pigs, for research purposes. This is an area of research involving xenotransplantation and genetic modification. Step 4: Conclusion
Since all three statements are correct, the correct answer is (4) I, II and III.
Answer: (4) I, II and III
