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 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%?
