Verified step by step guidance1
Understand the role of DNA in the cell: DNA (Deoxyribonucleic Acid) is the molecule that carries genetic information essential for the functioning, growth, and reproduction of all living organisms.
Identify the organelle responsible for storing and protecting DNA: The nucleus is the cell organelle that houses the DNA in eukaryotic cells. It is surrounded by a nuclear envelope, which protects the DNA and regulates the exchange of materials between the nucleus and the cytoplasm.
Eliminate incorrect options: The Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids. Lysosomes are responsible for breaking down waste materials and cellular debris. The endoplasmic reticulum (ER) is involved in protein and lipid synthesis, but it does not store DNA.
Confirm the correct answer: Since the nucleus is the organelle that contains DNA, it is the correct answer to the question.
Conclude: The nucleus is the major constituent of DNA in eukaryotic cells, making it the correct choice among the given options.
