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 substitution of Uracil in Rna [instead of â¦ Thymine] has the same effect-improved spacing; it most likely provides a 'unique identification' function as well, all those Dna and Rna polymerases need to have some way to direct them to their appropriate Job Sites.
