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 (a) and (b) neither chromatid was labeled both chromatids of a chromosome were labeled only one chromatid of a chromosome was labeled both (a) and (b) neither chromatid was labeled both chromatids of a chromosome were labeled ANSWER DOWNLOAD EXAMIANS APP
DNA Structure and Replication The replication of a linear DNA molecule in a eukaryotic chromosome creates a problem which is reported to be sorted out by using RNA as a template shortening of the double stranded replicated portion None of these using enzyme called telomerase using RNA as a template shortening of the double stranded replicated portion None of these using enzyme called telomerase ANSWER DOWNLOAD EXAMIANS APP
