Taylor conducted experiments to prove a semi-conservative mode of chromosome replication on:
Correct answer: B. Vicia faba
- A. Vinca rosea
- B. Vicia faba
- C. Drosophila melanogaster
- D. E. coli
Explanation
Taylor conducted his experiment on treated root tip cells of Vicia faba and treated them with radioactive thymidine (3H) to label the molecule of DNA, and then they grew them in the normal unlabelled medium, with colchicine, to see the semi-conservative nature of the chromosome replication. Semi-conservative mode of replication produces two copies of DNA, each copy containing one original strand and one new strand of DNA.

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.
