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.
Genetic information is stored in nucleic acids. Most organisms, including all animals and plants, store it in DNA, but some viruses store it in RNA. In a human cell, most of the genetic information is stored in the nucleus, in certain segments of the chromosomes.About 1 or 2 per cent of the length of human chromosomes consists of genes. The remaining information is in the DNA of each mitochondrion.n a human cell, most of the genetic information is stored in the nucleus, in certain segments of the chromosomes.
