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.
The synthesis of proteins takes two steps: transcription and translation. Transcription takes the information encoded in DNA and encodes it into mRNA, which heads out of the cellâs nucleus and into the cytoplasm. During translation, the mRNA works with a ribosome and tRNA to synthesize proteins.
