How is DNA stored in eukaryotic cells? Select the TWO answers that are correct.

Question

Quizplus · Accepted Answer

In eukaryotic cells, DNA is stored in the nucleus, which is separated from the cytoplasm by a double membrane called the nuclear envelope. Within the nucleus, DNA is organized into linear molecules called chromosomes, which are made up of DNA wrapped around proteins called histones. The histones help to condense the DNA and regulate gene expression. Thus, options A and D are correct as they correctly describe the storage of DNA in eukaryotic cells. Option B is partially correct, as chromosomes are made up of double-stranded DNA molecules, but they are not multiple in number - each chromosome consists of a single DNA molecule. Option C is incorrect, as chromosomes are composed of both DNA and protein molecules. Option E is incorrect, as circular DNA molecules are typically found in prokaryotic cells, not eukaryotic cells.
