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.
It is loaded with an amino acid and is ready to participate in translation at the ribosome, where it binds to the acceptor site. Aminoacyl-tRNA synthase-The enzyme that catalyzes the bond between specific tRNA and amino acid, to form aminoacyl tRNA. Anticodon arm-A secondary structural feature of tRNA.nticodon-The sequence of three nucleotides located on the anticodon arm of the tRNA cloverleaf structure. The anticodon bonds in antiparallel fashion with a codon of mRNA at the acceptor site of a ribosome during translation.
