#Unit 3. Fundamental Processes

Method for determining mRNA half-lives.
RNA polymerase II transcription is shut down, either by a drug or a temperature shift in strains with a temperature sensitive mutation in a Pol II gene. The levels of specific mRNAs are determined by northern blot or RT-PCR at various times following shutdown.

#Unit 3. Fundamental Processes

There are RNA polymerase crystal structures that provide considerable insight into how the enzyme retains contact with its substrate while breaking and remaking bonds in the process of the nucleotide addition cycle and undergoing translocation by a Brownian ratchet mechanism.

Mediterranean shrublands (chaparral):  These are located near an ocean and have wet, cool winters and hot, dry summers.  Rainfall is 40 to 100 centimeters per year. 
Fire is a common feature of this biome, and the shrubs are adapted to withstand occasional fires.
