A qualitative scheme mainly uses differences in color hue to indicate differences in the kind of some phenomenon (e.g., land use, crop type, religion, etc.). In a qualitative scheme, you will generally want to choose color hues that have approximately the same lightness and chroma level (see Figure 4.cg.15, below).
In the cytoplasm are molecules of tRNA. On one end of a tRNA molecule is the anticodon: a set of three bases that will match a certain codon. The other end of the tRNA can pick up and hold a certain amino acid. Each tRNA can only hold one kind of amino acid.
Transfer RNA. There is at least one tRNA for each type of amino acid. The tRNA is relatively small and resembles the configuration of a clover leaf. Each tRNA has a nucleotide triplet, called an anticodon.This anticodon is the opposite match for one codon on the mRNA.ransfer RNA. There is at least one tRNA for each type of amino acid.
