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.

WebThe replication complex is the group of proteins that help synthesize the new DNA strands. A replication unit is any chunk of DNA that is capable of being replicated — e.g. a plasmid with an origin of replication (ORI) is a replication unit.
