The sequence below represents one side of a DNA strand. GAA TTC GCA
What would the complimentary DNA strand be during the process of DNA replication?

CUU AAG CGU

GAA CCT CAT

CTT AAG CGT

GAA TTC GCA

GAA TTC GCA    Original strand

CTT AAG CGT    Complimentary strand

Explanation:

The original strand is already given.  It is GAA TTC GCA

Now we need to recognize the complementary strand from the pool of options and pair their bases. Names are written with their letters.

Nitrogenated bases that form nucleic acids correspond to purines and pyrimidines.

In the DNA molecule, Adenine (Purine) forms pairs with Timine (Pyrimidine), while Guanine (Purin) pairs with Cytosine. Two hydrogen bonds join the A-T pair, and three hydrogen bonds join the G-C.

Knowing this, we need to find the correct option, which will pair A with T and C with G.

G ⇔C

A ⇔ T

A ⇔ T

T ⇔ A

T ⇔ A

C ⇔ G

G ⇔ C

C ⇔ G

A⇔ T
