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.
Report Abuse. DNA and RNA are polymers made of monomeric subunits, called nucleotides, which can be linked together in any order. The nucleotide is the basic, repeated unit of DNA or RNA strand and contains a nitrogenous base-a double-ring purine or a single-ring pyrimidine, linked to phosphorylated sugar.The sugar with an attached base, but without a phosphate group is called a nucleoside.n DNA molecule, the sugar is 2â²-deoxyribose and in RNA molecule-ribose. The sugars comprise the backbone of every DNA or RNA chain, linked by covalent phosphodiester bond between 5â²- and 3â²-carbons of two adjacent sugars.
