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.
During transcription, the enzyme RNA polymerase synthesizes a strand of messenger RNA (mRNA) using one strand of the gene as a template.mRNA is synthesized using nucleotides that contain the bases A, C, G, and U (instead of T), which pair with the complementary bases of the DNA template strand.irst of all, since RNA polymerase synthesizes mRNA from 5' to 3' (just like DNA polymerase) the DNA template strand has to be read from 3' to 5' (just like when DNA polymerase uses a DNA template strand to synthesize a new complementary DNA strand).
