Question

If the sequence of bases in one strand of $DNA$ is $ATGCATGCA$, what would be the sequence of bases on complementary strand

• A. $ATGCATGCA$
• B. $AUGCAUGCA$
• C. $TACGTACGT$
• D. $UACGUACGU$

Answer 1

Answer: (C)

Adenine always pairs with thymine and cytosine always pairs with guanine. Thus, sequence of bases on complementary strand would be $TACGTACGT$.
