Which statement is true about DNA in eukaryotic cells?

• A. DNA is located in the nucleus as the cell's genetic material
• B. DNA is located in the cytoplasm only
• C. DNA is a protein
• D. DNA is not genetic material

Answer: (A)

DNA in eukaryotic cells is located in the nucleus, where it acts as the genetic material. The nucleus is enclosed by a membrane and organizes DNA into chromosomes, which allows precise control of replication and transcription. While a small amount of DNA is also present in organelles like mitochondria and chloroplasts, the bulk of genetic information resides in the nucleus. The cytoplasm contains the machinery for protein synthesis and other functions, but not the main genome. DNA is a nucleic acid made of nucleotides, not a protein, so the idea that DNA is a protein is incorrect. And because DNA carries genes and heredity, it is indeed genetic material, so saying it isn’t is false.
