Explanation:
Detailed explanation-1: -The upper strand of DNA is the “mRNA-like” strand. The lower strand is the strand that is complementary to the mRNA.
Detailed explanation-2: -If one strand of a DNA molecule has the sequence of bases 5’ATTGCA3’, the other complementary, antiparallel strand of DNA would have the sequence: 5’TGCAAT3’.
Detailed explanation-3: -Answer and Explanation: If a DNA strand has the sequence 5’-ATG-3’, the complementary messenger RNA (mRNA) sequence made using this DNA template would have the sequence 3’-UAC-5’.
