A) 5'UGCAAU3'
B) 5'TGCAAT3'

The other complementary strand of DNA molecule with base sequence 5'ATTGCA3' would be 5'TAACGT3'. Thus, the correct option would be D.

According to the base-pairing rule of Chargaff:

  • Adenine (A) always pairs with Thymine (T) in DNA or Uracil (U) in RNA
  • Guanine (G) always pairs with Cytosine (C)

Following this rule, a DNA sequence of ATTGCA in the 5' to 3' direction will have a complementary sequence of TAACGT in the same direction.
