Question

following statements are true for dou- hic which oded DNA? Explain your reasoning. The sym sranded DNA? Explai e-sarands for purine (A or G), and Y stands for vrimidine (C or T) py a) A+CG+T R=Y CHALLENGE PROBLEMS The mitotic chromosome illustrated here s observed after two rounds of DNA replication BUdR. The dotted lines represent the DNA strands in the DNA duplex present in each chromatid Explain what process might have resulted in such a pattern of fluorescence. Depict the BUdR labeling of each chromatid by (1) making the line solid if the strand is labeled with BUdR or (2) leaving it CHALLENGE PROBLEM 1 wa in the presence of dashed if it is not labeled with BUdR. CHALLENGE PROBLEM A cross involving four linked genes ABCDXa b c d) is made in budding yeast Saccharo- myces cerevisae. The genes B and C are eytremely close

Explanation / Answer

B.A +G =T+C.

According to charguff rule, the sum of purines (A+G) equals the sum of pyrimidines (C+T).
