Edwin Chargaff determined that the amount of adenine (A) is equal to the amount of thymine (T ) in a DNA sample. He also determined that the amount of cytosine (C) is equal to the amount of guanine (G). Thus, A always pairs with T and and C always pairs with G in the complementary DNA strand. Knowing this information, what would be the complementary strand of DNA for ATCGGC?

Demonstrate the proof of your new polynomial identity through an algebraic proof and a numerical proof in an engaging way! make it so the whole world wants to purchase your polynomial identity and can't imagine living without it! you must: label and display your new polynomial identity prove that it is true through an algebraic proof, identifying each step demonstrate that your polynomial identity works on numerical relationships create your own using the columns below. see what happens when different binomials or trinomials are combined. square one factor from column a and add it to one factor from column b to develop your own identity. column a column b (x − y) (x2 + 2xy + y2) (x + y) (x2 − 2xy + y2) (y + x) (ax + b) (y − x) (cy + d)
