Which of the following statements is/are correct? 1. Gene Editing deals with inserting genes from other organism while Gene Modification deals with altering genes that exists already within body. 2. Gene Modification process is time consuming while Gene editing is faster. Select the correct answer using the code given below. Correct Answer Neither 1 nor 2

The correct answer is Neither 1 nor 2.

Key Points

  • Gene editing:
    • Gene editing refers to a set of technologies that allow scientists to alter an organism's DNA.
    • These technologies enable the addition, removal, or modification of genetic material at specific sites in the genome.
  • Gene modification:
    • Gene modification, on the other hand, is the act of modifying an organism's genetic composition. For thousands of years, this has been accomplished indirectly through controlled, or selective, breeding of plants and animals.
    • Gene editing is less expensive, easier to use and more accurate than gene modification. Hence, statement 1 is not correct.
    • Gene Modification is faster than Gene Editing. Hence, statement 2 is not correct.
