How does gel electrophoresis work? Group of answer choices DNA is negatively charged. When an electrical current is passed throu
gh a gel, the DNA is repelled by the nearby negative current and pushed across the gel towards the positively charged side. DNA is positively charged. When an electrical current is passed through a gel, the DNA is repelled by the nearby negative current and pushed across the gel towards the positively charged side. DNA is negatively charged. When an electrical current is passed through a gel, the DNA is repelled by the nearby positive current and pushed across the gel towards the negatively charged side. DNA has no charge. When a current is passed through a gel, the DNA is repelled by the negative current and pushed across the gel towards the positively charged side.

Explanation:
Electrophoresis has become a standard molecular biology technique. This technique is based on the use of a constant-uniform electric field that enables the separation and identification of DNA fragments with different lengths, which form bands in the electrophoresis gel. Electrophoresis can be used to analyze not only DNA, but also RNA and proteins. During electrophoresis, the fragments of DNA that are negatively charged will migrate towards the positively charged electrode, where the duration of this movement will depend on the size of the DNA fragment, as well as of the pore size in the gel.
Both promoters and enhancers are generally regulating transcription. They are not regulating in translation. They are not responsible for regulation in translation.
Transcription machinery assemble at naked eukaryotic DNA. They do not assemble at DNA chromatin.
The total number of chromosomes present in the human cell before meiosis would be four. Meiosis<span> is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. Hope this helps. Have a nice day.</span>
