DNA polymerase is the main enzyme in DNA replication. Requirements: It depends on Mg 2+ ions and ATP/NAD + cofactors: It depends on a template, nucleotides, primers and Mg 2+. Functions: DNA ligase is important for DNA recombination, DNA repair and DNA replication. DNA polymerase is important for DNA replication, DNA repair and DNA recombination technology.
Cyanosis can be central where the bluish discoloration of the skin is evident on the face, particularly the mouth and tongue, or it may be peripheral where it is only evident in the arms and legs, particularly the fingertips and toes, and even the ears. What does cyanosis mean?
Skin discoloration is a common condition that occurs mostly from sun exposure, and leads the skin to become darkened in certain areas or patches. These areas, usually brown, are a collection of pigment called melanin. Melanin is produced by the skin, and absorbs ultraviolet rays to protect the body from the sun. Increased melanin leads to increased discoloration.
