Answer:

D) 3' TGTAGTGCGCGCGT 5'

Explanation:

DNA strand:   5' ACATCGACGCGCGCA 3'

compliment:  3' TGTAGCTG CGCGCGT 5'

DNA strands are antiparallel which means that if you're given a 3' to 5' strand, the complementary DNA strand will be 5' to 3'. If you are given a 5' to 3' strand, the complementary strand will be from 3' to 5'.

The other thing to remember for DNA complementary strands only is:

- A always pairs with T

- G always pairs with C

(for DNA only!!!!) This is one of Chargaff's principles.

If you're asked to find the RNA sequence, A pairs with U. not T! Thymine does not apply to RNA. G still pairs with C though.
