Question

If a strand of DNA of sequence 5’-AATAGCGCGGTATTC-3’ is replicated, which of the following accurately represents the newly synthesized DNA strand?

Answer 1

TTATCGCGCCATAAC. I hope I answered that right. 

Answer 2

3'-TTATCGCGCCATAAG-5'

Step-by-step explanation:

Four Nitrogenous bases are found in DNA. They are:

1- Adenine

2- Guanine

3- Cytosine

4- Thymine

Adenine pairs with Thymine and Guanine with cytosine on the complementary strand.

During replication, a complementary strand to the one which is being replicated is synthesized.

So for the strand of DNA in question the following strand will be synthesized:

3'-TTATCGCGCCATAAG-5'.
