WebSep 9, 2024 · 2. No, replication cannot happen in the absence of polymerase (on the timescales relevant to humans). You are correct that in PCR, the first step is to separate DNA strands at 98 C. This heating dissociates the strands semi-permanently. So when you cool down the reaction, the strands do not re-associate very quickly. WebWhat type of nucleic acid is represented by green, AND why is this needed? RNA, because it tells DNA polymerase to build new strands. D.
