Each rung of the ladder is made of two molecules called bases, forming a base pair. There are four types of DNA bases: adenine (A), thymine (T), guanine (G), and cytosine (C). The bases always pair up according to these rules:<\/p>\n                                    <ul>\n                                        <li>A pairs with T<\/li>\n                                        <li>C pairs with G<\/li>\n                                    <\/ul>\n                                    <p>The two vertical sides of the ladder are made of alternating sugar (S) and phosphate (P) molecules. The combination of a sugar, a phosphate, and a base is called a nucleotide.<\/p>\n                                    <p>These nucleotides are connected together into long DNA sequences.

Sometimes that's true, but it's usually more complicated than that. Take eye color, for example: many genes play a role in creating the color pigments in the eye, and genetic variants in any of them can affect your eye color.<\/p>\n                                    <p>This can also be true for diseases.

Alone, each of them only have a tiny impact on risk of developing type 2 diabetes, but together they can add up to an overall higher risk.<\/p>\n                                    <p class=\"text-center\">\n                                        <button type=\"button\" class=\"checkpoint\">Checkpoint<\/button>\n                                    <\/p>\n                                <\/div>\n                                <div class=\"content-checkpoint\">\n                                    <div class=\"question\">Traits are determined by _______.<\/div>\n                                    <div class=\"answer-container\">\n                                        <button type=\"button\" class=\"answer-button\">A.
