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.
Uracil is found in RNA and binds to adenine via 2 hydrogen bonds, but is replaced by thymine in DNA. Methylation of Uracil produces thymine. Uracil can pair with any of the base pairs depending on arrangement. Despite this, it readily pairs with adenine because the methyl group is repelled into a fixed position. In the uracil and adenine bond, uracil is the hydrogen bond acceptor and the adenine is the donor. When attached to a ribose sugar, the compound is called uridine, a nucleoside. Then, phosphate attaches to uridine to form uridine 5'-monophosphate.
