#Unit 3. Fundamental Processes

Class I enzymes attach the amino acid to the 2’-OH of the tRNA and are generally monomeric. Class II enzymes attach the amino acid to the 3’-OH of the tRNA and are typically dimeric or tetrameric.The amino acids for which the Class I synthetases are specific tend to be larger and more hydrophobic than those for Class II synthetases.

#Unit 6. System Physiology – Plant

One plant produced sesquiterpene, (E)‐β‐farnesene (EBF), has been considered a potential defense against aphids, since its emission by plants causes aphids to drop off the plant or depart from the feeding site.
