The unequivocal proof of DNA as the genetic material came from the studies on a:
Correct answer: D. Bacterial virus
- A. Bacterium
- B. Fungus
- C. Viroid
- D. Bacterial virus
Explanation
Avery, MacLeod, and McCarty first established that DNA was the genetic material by working on the same bacteria as Griffith. However, they could not convince all the biologists. The unequivocal proof that DNA is the genetic material came from the experiments performed by Alfred Hershey and Martha Chase. They worked with bacteriophages (virus that infects bacteria). The unequivocal proof that DNA is the genetic material came from the experiments of Alfred Hershey and Martha Chase (1952). They worked with viruses that infect bacteria called bacteriophages.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
