Question

The diagram represents a portion of one strand of a DNA molecule.


This representation shows a single DNA strand. Only seven bases are shown: ACGTACC


Which of the four DNA strands match the strand in the diagram by base pairing?


A. GGTGACT

B. TTGTCAG

C. GGTCGAT

D. CCTAGTG

Answer 1

TGCATGG because A pairs with T ( I remember with apples in the tree) and C pairs with G ( I remember this one with cars in the garage)

Answer 2

The answer is A. GGTGACT because C always pairs with G (I remember this as the lines are curved) and A always pairs with T (I remember this as all the lines are straight). So every time C pops up the complementary base pair is G and T with A.
