Given the following gene sequence showing the coding, non-template strand (bold is promoter), what is the sequence of the transcribed RNA? 

Briefly explain one method used by cells to quickly and reversibly convert an enzyme from an inactive to an active state.  

A cross between two nematode roundworms, one that moves normally and one that rolls in circles, results in 50% offspring with normal motion and 50% offspring that roll in circles. A.  Predict the genotypes of the parent worms. (2 points) B.  Explain your reasoning.  Include a Punnett square (use the “insert table” function) that supports your prediction (4 points).

For each of these processes, list each letter along with whether that process is present in prokaryotes only, eukaryotes only, both prokaryotes and eukaryotes, or neither. RNA is synthesized in the 5′ to 3′ direction. Transcription can be regulated by cis-acting proteins. Transcription occurs at the same time as RNA processing. Transcription can be regulated by attenuation.

Which of the following molecules would be likely to block division of cells expressing a MAPK mutant that is always active? Assume that the MAPK mutant is the only mutation in these cells.

Which of the following is a typical requirement for cancer development?
