DNA (deoxyribonucleic acid) is the molecule that conveys genetic information for an organism's development and function. DNA is made up of two connected strands that loop around each other like a twisted ladder, giving it the shape of a double helix. The backbone of each strand is made up of sugar (deoxyribose) and phosphate groups that alternate. Each sugar has one of four bases attached to it: adenine (A), cytosine (C), guanine (G), or thymine (T).

Read the summary of the Fourteenth Amendment of the U.S. Constitution.Passed by the Senate on June 8, 1866, and ratified two years later, on July 9, 1868, the Fourteenth Amendment granted citizenship to all persons "born or naturalized in the United States," including formerly enslaved people, and provided all citizens with equal protection under the laws, extending the provisions of the Bill of Rights to the states. The amendment authorized the government to punish states that abridged citizens right to vote by proportionally reducing their representation in Congress. It banned those who engaged in insurrection against the United States from holding any civil, military, or elected office without the approval of two-thirds of the House and Senate. The amendment prohibited former Confederate states from repaying war debts and compensating former slave owners for the emancipation of their enslaved people. Finally, it granted Congress the power to enforce this amendment, a provision that led to the passage of other landmark legislation in the twentieth century, including the Civil Rights Act of 1964 and the Voting Rights Act of 1965. Congress required former Confederate states to ratify the Fourteenth Amendment as a condition of regaining federal representation.Based on this, which detail from the "Address to the Niagara Movement" deals with the application of constitutional principles?
