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 only one chromatid of a chromosome was labeled both chromatids of a chromosome were labeled both (a) and (b) neither chromatid was labeled only one chromatid of a chromosome was labeled both chromatids of a chromosome were labeled both (a) and (b) neither chromatid was labeled ANSWER DOWNLOAD EXAMIANS APP
