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.
1 RNA polymerase creates a transcription bubble, which separates the two strands of the DNA helix. This is done by breaking the hydrogen bonds between complementary DNA nucleotides.  RNA polymerase adds RNA nucleotides (which are complementary to the nucleotides of one DNA strand).
