The lectin contents in some parts of plants are higher, e.g., 390 and 75 mg of the purified lectin was recovered from 100 g Remusatia vivipara tubers (Bhat et al. 2010) and Astragalus mongholicus roots (Yan et al. 2005), respectively. Lectins are also found in seeds.
The sequence of bases on the RNA forms a code for the amino acid building blocks of the protein. The word translation seems particularly appropriate for this process since the information contained in the DNA is translated from the four-character alphabet of the bases to the twenty-character alphabet of the amino acids. The construction of the proteins is carried out on the ribosomes of the host cell.
When a stop signal is reached, the entire complex disassociates. The ribosome, the mRNA, the tRNAs and the enzymes are then either degraded or re-used for another translational event. Translation of the DNA/RNA code into a sequence of amino-acids is just the beginning of the process of protein synthesis. The exact sequence of amino-acids in a polypeptide chain is the primary structure of the protein.
