DNA Structure and Replication Taylor, Woods and Hughes labeled Vicia DNA by allowing new DNA synthesis in the presence of radioactive thymine. After DNA replication (S phase of the cell cycle), it was observed that neither chromatid was labeled both chromatids of a chromosome were labeled both (a) and (b) only one chromatid of a chromosome was labeled neither chromatid was labeled both chromatids of a chromosome were labeled both (a) and (b) only one chromatid of a chromosome was labeled ANSWER DOWNLOAD EXAMIANS APP
