As a matter of fact, Mexican men and women develop a strong attachment to their mothers and families, but the relationship is quite different for sons and daughters. The relationship between mother and daughter transitions between absolute love and absolute hate with relative ease.
Bacteria [edit]. In bacteria, the RNA polymerase holoenzyme is made up of two parts, a core polymerase and a sigma factor. The core polymerase has the components needed for elongation in transcription, while the sigma factor is only needed for transcriptional initiation.NA polymerase have a multitude of structural features that help in the transcription process. A Structure known as the clamp keeps the polymerase anchored to DNA. The flap ensures that the MRNA is retained. The rudder prevents DNA/RNA hybrid from occurring. DNA does not enter the mouth of the polymerase directly.
see pcr1. RNA polymerase. 1. an enzyme that synthesizes an RNA copy of the sequence in a limited region of DNA in a process known as DNA transcription. Called also DNA-dependent RNA polymerase. 2. a viral enzyme that synthesizes RNA from an RNA template during viral replication. Called also RNA-dependent RNA polymerase. see RNA polymerase (above). Taq polymerase. a DNA polymerase that functions at high temperature; derived from the bacterium Thermus aquaticus and used in the polymerase chain reaction.
