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 both (a) and (b) only one chromatid of a chromosome was labeled both chromatids of a chromosome were labeled neither chromatid was labeled both (a) and (b) only one chromatid of a chromosome was labeled both chromatids of a chromosome were labeled neither chromatid was labeled ANSWER DOWNLOAD EXAMIANS APP
DNA Structure and Replication In the study of one experiment it was found that the value of Tm for DNA is = 40° C. If the cell has 20% GC at the above Tm, then what will be value of 'Tm' if the GC% increases to 60%? Increases Can not be compared Remains same Decreases Increases Can not be compared Remains same Decreases ANSWER DOWNLOAD EXAMIANS APP
