Question

Which of the following is complementary to the DNA sequence 5' ATTGCACCGG 3' ?

A 5' CCGGTGCAAT 3'
B 5' TAACGTGGCC 3'
C 3' CCGGTGCAAT 5'
D 3' GGCCACGTTA 5'

Answer 1

A) 5' CCGGTGCAAT 3'

Step-by-step explanation:

A pairs with T, G pairs with C. This strand runs in the antiparallel direction, so the DNA strands would look like this:

5' ATTGCACCGG 3'

3' TAACGTGGCC 5'
