I have no idea how to do this, I daydreamed during class and made a big mistake.

I don't understand #'s 9-19
Thank you so much if you can answer it,
10 Points to best answer :)

daydreamed uh lol Hey we all have done that.

9. Adenine and Thymine... Guanine and Cytosine
10. A goes with T, G goes with C... so if 4 G's than it has 4 C's.
11. a. Yes you have 4 C's
b. Adenine, Thymine, Cytosine, Cytosine, Guanine
12. Yes
13. Same
14. Two of each
15. Yes
16. Yes
17. I dont know what the question is asking.. sorry
18. Thymine
19. a. Cytosine b. Uracil C. Guanine D. Adenine


Sorry if i missed anything, double check them and Good Luck...


P.S. Next time dont day Dream in class.

9. AT (adenine,thymine) and GC (guanine and cytosine)
10. 4
11.A-yes, B- Thymine-Adenine, Adenine-Thymine,Guanine-Cytosine,Guanine…
12.Yes
13.Same
14.6
15.Yes
16. Yes
17. im a little unsure but i think it would be DNA
18.Thymine
19.Guanine-Cytosine, Adenine-Uracil, Cytosine-Guanine, Uracil-Adenine
