Genetics majors only please!!Which of the conditions below is necessary for DNA to be replicated semi conservatively? a. purines exceed pyrimidiness purines pair with purines b. purines equal pyrimidines: purines and pyrimidines pair randomly c. pyrimidines exceed purines; pyrimidines pair with purines d. purines equal pyrimidines purines pair with p pyrimidines pair with e. purines equal pyrimidines purines pair with purines and pyrimidines is based on cellular DNA, replication process, with a specific feature that from cellular DNA replication. This feature is and it is caused differs by a, chain extension: altered bases b, chain extension; additional bases chain termination; altered bases. chain reaction; fluorescent molecules chain termination; additional bases
Explanation / Answer
Which of the condition below is necessary for DNA to be replicated semi-conservatively?
b. purines equal to pyrimidines; purines and pyrimidines pair randomly.
According to Chargraff's rule due to complementary base pairing the total number of purine bases is always equal to total number of pyrimidine bases in ratio (1:1). This is why in semi-conservative replication of DNA purines are equal to pyrimidine and they pair randomly.
