In chrosomes, the material controlling heredity is ________ ?
Correct answer: A. DNA
- A. DNA
- B. Histones
- C. Chromocentres
- D. RNA
Explanation
DNA is the hereditary material in chromosomes because its nucleotide sequence stores the instructions transmitted from parents to offspring. Histones help package DNA, but they do not carry the genetic code, so students may select histones if they confuse structural support with genetic information.
