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.
This genetic information is found in the nucleus, though protein synthesis actually occurs in ribosomes found in the cytoplasm and on rough endoplasmic reticulum. If protein is to be synthesised, then the genetic information in the nucleus must be transferred to these ribosomes. This is done by mRNA (messenger ribonucleic acid). It is very similar to DNA, but fundamentally differs in two ways. 1  A base called uracil replaces all thymine bases in mRNA.
