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.
Codons are read from the first position at the five prime end to the third position at the three prime end. Anticodons Anticodons are three-segment nucleotides that correspond to codons. In DNA, anticodons are read backward in comparison to codons, starting at the three prime end and ending at the five prime end. These are found in the transfer RNA and help to align amino acids with the corresponding messenger RNA codons during protein production to build a complex protein or a polypeptide.
