Answer: DNA ligase.
Explanation:
Polymerase chain reaction is a technique used in molecular biology by scientists to make several copies of a DNA sample which enable them to take a smaller portions of it and expand it for more detailed study.
PCR mixture is premixed and contain thermostable DNA polymerase, oligonucleotides primer, four deoxynucleodide triphosphates, Magnesium chlorides, a propietary buffer.
Capillary action<span> (sometimes </span>capillarity<span>, </span>capillary motion<span>, or </span>wicking<span>) is the ability of a </span>liquid<span> to flow in narrow spaces without the assistance of, or even in opposition to, external forces like </span>gravity<span>. The effect can be seen in the drawing up of liquids between the hairs of a paint-brush, in a thin tube, in porous materials such as paper and plaster, in some non-porous materials such as sand and liquefied </span>carbon fiber<span>, or in a cell. It occurs because of </span>intermolecular forces<span> between the liquid and surrounding solid surfaces. If the diameter of the tube is sufficiently small, then the combination of </span>surface tension<span> (which is caused by </span>cohesion<span> within the liquid) and </span>adhesive forces<span> between the liquid and container wall act to propel the liquid.</span><span>[1]</span>
A, B, D, F are the gated embedded
proteins in model 1 allow potassium ions through the membrane. Sodium ions are
necessary for regulation of blood and body fluids, transmission of nerve
impulses, heart activity, and certain metabolic functions. Physiologically, it
exists as an ion in the body.
