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 only difference is the fact that thymine is replaced by Uracil. The amino acids that are brought to the ribosome by tRNA then bind to each other through peptide bonds, eventually forming a polypeptide chain (the beginnings of a protein). Thus, we can see how DNA codes for RNA which then codes for specific amino acids.
