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.
It is the sequence of these four bases along the backbone that encodes information. This information is read using the genetic code, which specifies the sequence of the amino acids within proteins. The code is read by copying stretches of DNA into the related nucleic acid RNA, in a process called transcription.
