Question

Genetic engineering involves manipulation in

• A. DNA
• B. RNA
• C. Gamete
• D. Protein

Answer 1

The correct option is A

DNA

The correct option is A.

Explanation of correct option:

1. DNA is the source of all information in an organism.
2. It stores all the information and hence in order to alter a piece of information changes need to be made to the DNA.
3. Genetic engineering can be described as the process of obtaining the desired character in an organism by changing its DNA makeup.

Explanation of incorrect option:

Option B:

1. RNA is an unstable nucleotide and hence making any changes in this won't help in changing the character.

Option C:

1. Gametes are produced from each parent which contains the DNA having all the information about the parent.

Option D:

1. Proteins cannot be manipulated for genetic engineering as because proteins are not a part of information-carrying molecules.
2. Proteins help in making the DNA compact to store within a cell.

Final answer:

Genetic engineering involves the manipulation of DNA.
