The electrical current created during gel electrophoresis forces DNA to move from the negative end to the pos tive end. Which of the following statements accurately describes why this happens?* O Molecules always move down their electrical gradient, from negative to positive. The backbone of DNA is negatively charged, forcing it to move towards the positive end. Since DNA is loaded into wells at the negative end, the only direction they can move is towards the positive end. The backbone of DNA is positively charged, forcing it to move towards the positive end.

Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
