Pruritus most frequently is an unpleasant symptom of a clinically evident dermatologic condition (Table 1) . 1 â 3, 11, 12 The itch of dry skin, otherwise known as xerosis or asteatotic eczema, is common in older adults. 3, 11, 12 Xerosis occurs most often during the winter in northern climates.TOPIC DERMATITIS. Atopic dermatitis can result in severe pruritus and is often described as âthe itch that rashes (when scratched).â Atopic dermatitis affects 10 percent of children and often develops before six months of age.
What is DNA Polymerase? The DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two identical DNA strands from one original DNA molecule. During this process, DNA polymerase âreadsâ the existing DNA strands to create two new strands that match the existing ones.
DNA polymerases are a family of enzymes that carry out all forms of DNA replication. DNA polymerases in general cannot initiate synthesis of new strands, but can only extend an existing DNA or RNA strand paired with a template strand.NA polymerase III (in prokaryotes) or Pol Î´ (in eukaryotes) is responsible for extension of the primers added during replication of the lagging strand. Primer removal is performed by DNA polymerase I (in prokaryotes) and Pol Î´ (in eukaryotes).
