DNA CODE Multiple options ​
Kruka [31]

Answer:

TAGGCAATCGCCATATTG

Explanation:

T matches with A

C matches with G

Think about it like this, T is a nerdy boy, C is a jock boy, A is a nerdy girl, and G is a jock girl.

If you were a matchmaker in your high school, you'd pair the nerds (A&T) together and the jocks (C&G) together so they'd have common interests and get along well, right?

It's the same with DNA, T&A get along well, and so do C&G.

Hope this helps <3
