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.
An organism's genetic information is encoded as a linear sequence of bases in the cell's DNA. During the process known as transcription, a RNA copy of a segment of DNA, or messenger RNA (mRNA), is made. This strand of RNA can then be read by a ribosome to form a protein.RNAs also play important roles in protein synthesis, as will be discussed in the ribozyme section, as well as in gene regulation.roteins are the workhorse of the cell and carry out diverse catalytic and structural roles, while the nucleic acids, DNA and RNA, carry the genetic information that can be inherited from one generation to the next.
