Which of the following could be the second strand of DNA where the first strand has the sequence 5' - CTTAGC - 3'? 5' - GCTAAG - 3' 5' - CGATTC - 3' 5' - CTTAGC - 3' 5' - GAATCG - 3' Question 2 If 27% of the bases in a double-stranded DNA molecule are A, which of the following must be true? Chose the single best answer. Its bases must be 27% C. Its bases must be 27% T and 23% G. Its bases must be 27% T and 27% C. Its bases must be 23% G. Its bases must be 27% T.
