WebSimilar to DNA replication that occurs under normal biological conditions, the PCR requires a DNA polymerase to make the new strands of DNA. The polymerase that is used in the PCR reaction is called “ taq polymerase”, as it was originally isolated from the heat-tolerant bacterium T hermus aq uaticus that normally live in hot springs and ... WebMar 1, 2024 · The two main steps in gene expression are transcription and translation. Transcription is the name given to the process in which DNA is copied to make a complementary strand of RNA. RNA then undergoes translation to make proteins. The major steps of transcription are initiation, promoter clearance, elongation, and termination.
