What structure is formed from a phosphate unit, a ribose, and uracil? (multiple choice)

if you google nucleic acids:blueprints of life you'll see the structure. Its question one of post lab questions.

The three possible answers are an amino acid base, portion of messanger RNA, or deoxyribonucleotide.

I'll choose best answer right away.

Thanks!!

portion of messenger RNA!
Always remember that Uracil is unique for RNA! Uracil replaces thymine which is in the DNA!
RNA is a ribose=pentose its molecular formula is C5 H10 O5, while DNA is a Deoxyribose which means an oxygen is removed(C5 H10 O4)
It also has a phosphate unit!

portion of messenger RNA. it's the most likely since RNA standes for ribosenucleic acid, so it can't be DEOXYribonucleotide. And amino acids don't have a ribose.

Danny, the better key to it not being DNA is that there is uracil, which is in mRNA, but not in DNA.
