DNA Structure and Replication Which of the following is used to determine the appropriate stringency (Wallace rule)? Tm = 4 x (No.of A:T base pair) + 2 x (No.of G:C base pair) Tm = 2 x (No.of G:C base pair) + 4 x (No.of A:T base pair) Tm = 69.3° + 0.41 (%)G+C -650/1 Tm = 4 x (No.of G:C base pair) + 2 x (No.of A:T base pair) Tm = 4 x (No.of A:T base pair) + 2 x (No.of G:C base pair) Tm = 2 x (No.of G:C base pair) + 4 x (No.of A:T base pair) Tm = 69.3° + 0.41 (%)G+C -650/1 Tm = 4 x (No.of G:C base pair) + 2 x (No.of A:T base pair) ANSWER DOWNLOAD EXAMIANS APP

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