Question

PLEASE HELP ASAP!!!!!!!!!!! WILL MARK BRAINLIEST!!!!!!!!!!!!

You just finished learning about DNA replication. You are looking at the portion of a DNA strand of bacteria with a sequence of 5'-ATGTTCG-3'. What is the sequence of the complementary strand? What rule will you follow to make sure your answer is absolutely correct?

Answer 1

Answer:

The answer to your question is  3'- TACAAGC -5'

Explanation:

Original strand              5' - ATGTTCG - 3'

Complementary strand = ?

Just remember Nitrogenous bases

Adenine     attach to Thymine                 Thymine attach to  Adenine

Guanine     attach to Cytosine                 Cytosine attach to Guanine

Then, the complementary sequence will be

                                   3'- TACAAGC -5'

Answer 2

Answer:

the complimentary strand must have the sequence: 3'-TCCAGGC-5'. This ensures that A only pairs with T, and C only pairs with G.
