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.
Key Concepts: Bacterial DNA polymerase I enzymes are multidomain proteins with separate polymerisation, proofreading and 5â²â3â² exonuclease functions. They perform a vital function in bacteria by carrying out DNA repair and some aspects of chromosomal replication.Polymerases incorporate one nucleotide at a time to the 3â² end of the primer DNA strand in a templateâdirected manner.hey perform a vital function in bacteria by carrying out DNA repair and some aspects of chromosomal replication.
