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.
1 Messenger RNA (mRNA) transcribes genetic information from the DNA found in a cell 's nucleus, and then carries this information to the cell's cytoplasm and ribosome. 2  Transfer RNA (tRNA) is found in a cell's cytoplasm and is closely related to mRNA as its helper.NA's genes are expressed, or manifested, through the proteins that its nucleotides produce with the help of RNA. The information found in DNA determines which traits are to be created, activated, or deactivated, while the various forms of RNA do the work.
