The idea that eukaryotic chromosomes replicate semiconservatively was supported by Taylor et al,in experiments using ³H-thymidine labeled DNA from ______:

A) E. coli , and saw that the DNA was of intermediate density after one round of replication
B) Vicia faba, and saw that only one of the chromatids of each pair was radioactive after a second round of c-metaphase.
C) Vicia faba , and saw that only one of the chromatids of each pair was radioactive after a single round of c-metaphase.
D) E. coli , and saw that the DNA was of light density after one round of replication
E) None of these
