Answer:
DNA fragments are negatively charged so the more for the positive electrode because all DNA fragments of the same amount of charge per mass does smart pigments move through the gel faster than large one

Answer:
Gene expression is the process by which the instructions in our DNA are converted into a functional product, such as a protein. ... It acts as both an on/off switch to control when proteins are made and also a volume control that increases or decreases the amount of proteins made.
Explanation:
DNA is generally tightly packed into a structure called chromatin. It is double stranded and twisted into a structure called a double helix. In order to replicate, DNA must unwind. After unwinding, each side of DNA separates by unzipping down the middle, with the two unzipped strands serving as templates for creating new strands. At the end of replication, the two new segments of DNA each contain one old and one new strand.
Replication occurs at different rates in different types of cells. Some cells continuously divide and must constantly replicate their DNA. Other cells divide at a much slower rate and do not need to replicate their DNA as often. Some cells divide until the organ they make up reaches its normal size, and then they do not divide again.
DNA stands for deoxyribonucleic acid. Each strand of DNA is made up of a sugar, a phosphate and a nitrogenous base bonded together into a structure called a nucleotide. Many nucleotides bond together to form DNA.
