Semiconservative dna - Study guides, Class notes & Summaries

DNA replication is semiconservative, which allows each of the 2 strands to serve as a template for the new strands Correct Answer- true Recall that the DNA polymerase must bind a double-stranded polymer before it can start making its own DNA polymer. What helps the DNA polymerase to overcome this problem in DNA replication? Correct Answer- RNA primers Several components of cigarette smoke, including benzopyrene, insert themselves into the DNA and lead to several types of mutations such as...
