Assume that two strands of DNA have been separated and that the base sequence on one strand is AGCC. What is the sequence of bases on the complimentary strand of DNA?

a
GCTT
b
AGCC
c
TACA
d
TCGG
The correct answer is c) TACA.
In DNA, the bases Adenine (A) always pairs with Thymine (T), and Guanine (G) always pairs with Cytosine (C).
Therefore, the base sequence on the complimentary strand of DNA would be the pairing bases:
A - T
G - C
C - G
C - G
So, the complementary strand of DNA would be TACA.
