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.
DNA is made up of nucleotides, and proteins are made up of amino acids. The information in DNA is first transcribed into messenger RNA (mRNA) , which is also made up of nucleotides. The process of converting the genetic message found in mRNA to an amino acid sequence (protein synthesis) is called translation.longation continues in this fashion until the stop codon is reached and the peptide chain is released from the ribosome. Translation of proteins involves a mRNA, tRNA, ribosome, and energy. Click on the graphic to learn about translation with the Protein Synthesis animation.
