For a certain reaction: reactants –> products.  Ea is 85 kJ/mol. If the rate constant for the reaction is 3.3 x 10-3 s-1 at 25ºC, what is the rate constant at 30ºC?  

Fill in the blanks with the correct term: This structure is known as:   The foundational molecule for steroids is The carbon location on a steroid most often modified is Anabolic steroids are often synthetic versions of  

Match each type of RNA to its purpose:  

In a relaxed B form of DNA there are base pairs per turn of the helix.  Therefore the linking number of a strand containing 350 bp would be .  The type of enzyme that can relax a supercoiled DNA strand is called a .  In the packing of DNA into Chromosomes, The DNA is first supercoiled around and then further packaged into a . Finally, the structure is further condensed into before being duplicated into a chromosome.   NOTE: Only 1 word or number per blank please.
