DNA not contained in the nucleus that is passed from one generation to the next is

• A. Non-nuclear DNA
• B. Nuclear DNA
• C. Mitochondrial DNA
• D. Chloroplast DNA

Answer: (A)

DNA outside the nucleus refers to genetic material housed in organelles like mitochondria and chloroplasts. These genomes are inherited by offspring through the cytoplasm rather than via the nuclear genome, so they are passed from generation to generation even though they’re not in the nucleus. That makes the broad term non-nuclear DNA the best fit, since it encompasses both mitochondrial and chloroplast DNA. Nuclear DNA, by contrast, stays inside the nucleus, which is why it doesn’t match the description. Mitochondrial and chloroplast DNA are real examples of non-nuclear DNA that are inherited, but the general category described is non-nuclear DNA.
