Well, Africa is a continent and doesnât have a flag. If referring the the Pan African Flag, the color red represents the blood which shed for liberty. Black is the color of the race. Green is the color of the land (Motherland).
Uracil /ËjÊÉrÉsÉªl/ (U) is one of the four nucleobases in the nucleic acid of RNA that are represented by the letters A, G, C and U. The others are adenine (A), cytosine (C), and guanine (G). In RNA, uracil binds to adenine via two hydrogen bonds. In DNA, the uracil nucleobase is replaced by thymine. Uracil could be considered a demethylated form of thymine. Uracil is a common and naturally occurring pyrimidine derivative.
The uracil base replaces thymine in RNA. Thymine and uracil are structurally very similar. Uracil has fundamentally the same structure as thymine, with the deletion of a methyl group at the 5' position. Uracil will base pair with adenine in the same way as thymine pairs with adenine ().
