For a long time, plant lectin research concentrated on (i) the isolation and characterization of new carbohydrate binding proteins with interesting sugar binding and biological activities and (ii) the elucidation of the physiological role of different types of lectins from different species/taxa.
genetic code, the information carried by DNA that determines the specific amino acids and their sequence in each protein synthesized by an organism. The code consists of the sequence of nucleotides in the DNA molecule of each chromosome in the nucleus of every cell.
DNA has three primary attributes that allow it to be far better than RNA at encoding genetic information. First, it is normally double-stranded, so that there are a minimum of two copies of the information encoding each gene in every cell.
