What type of genetic transfer was displayed in the Frederick Griffith experiment?
Correct answer: B. Transformation
- A. Transduction
- B. Transformation
- C. Binary fission
- D. Conjugation
Explanation
Option A: Transduction is a method of genetic transfer in bacteria mediated by bacteriophages (viruses that infect bacteria). It involves the transfer of genetic material from one bacterium to another through the infection of a bacteriophage. This process was not demonstrated in the Frederick Griffith experiment. Option B: The Frederick Griffith experiment demonstrated bacterial transformation, where genetic material from one bacterium is taken up and incorporated by another bacterium, leading to a change in its characteristics. Option C: Binary fission is a form of asexual reproduction in which a single cell divides into two identical daughter cells. It does not involve the transfer of genetic material between different bacteria. Option D: Conjugation is a process of genetic transfer in bacteria that involves the direct physical contact between two bacterial cells. Conjugation was not observed in the Frederick Griffith experiment.

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.
