What is gel electrophoresis? – YourGenome

WebGel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode. Because all DNA fragments have the ... Webmaryannlauresta Answer: Ultracold polar molecules have been created by research scientists. These “molecules” consists of Rb and K atoms excited by lasers to form a type of Rb-K compound where the Rb has a positive charge and the K has a negative charge. The material is formed at temperatures extremely close to absolute zero. In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end. Polar molecules must contain one or more polar bonds due to a difference in electronegativity between the bonded atoms. Molecules containing polar bond… deadline to apply for covered california
