Abstract
Some sequences of RNA can catalyze biochemical reactions, much like protein enzymes. These catalytic RNA sequences are called ribozymes. The function of a ribozyme depends upon the primary sequence of the RNA which folds into a 3-D structure. How do different ribozyme sequences fold? You can search for ribozyme sequences using Entrez BLAST (NCBI, 2006). Then you can use a program like MFOLD (http://bioweb.pasteur.fr/seqanal/interfaces/mfold-simple.html) to submit your sequence for an analysis of its predicted 3-D structures based upon thermodynamics (Zuker, 2006; Zuker, 2003). Compare the different predicted structures and see if they are similar or different. If possible, compare the predicted structures to a published crystal structure. How close was the predicted structure to the crystal structure? Can you identify primary sequence elements in your molecule that contribute to parts of the structure? For example, palindromic stretches can form stem-loop structures. You can also mutate the sequence and submit the new sequence to MFOLD. How does this alter the 3-D structure? Can you use this computational method to identify potentially important nucleotides?Bibliography

Biochemist Growing, aging, digesting—all of these are examples of chemical processes performed by living organisms. Biochemists study how these types of chemical actions happen in cells and tissues, and monitor what effects new substances, like food additives and medicines, have on living organisms. |

Agricultural Technician As the world's population grows larger, it is important to improve the quality and yield of food crops and animal food sources. Agricultural technicians work in the forefront of this very important research area by helping scientists conduct novel experiments. If you would like to combine technology with the desire to see things grow, then read further to learn more about this exciting career. | |

Biological Technician What do the sequencing of the human genome, the annual production of millions of units of life-saving vaccines, and the creation of new drought-tolerant rice varieties have in common? They were all accomplished through the hard work of biological technicians. Scientists may come up with the overarching plans, but the day-to-day labor behind biotech advances is often the work of skilled biological technicians. | |||
