Draw an arrow showing the direction of synthesis of the new strand. To get at this questions, you compare the expression levels of mRNA in osteosarcoma cells and normal osteoclast cells. You find 17 mRNA's are in from 20-50 fold excess in cancer cells over normal cells. You sequence a part of each. I'd be happy to show you.
Cancer cells are cells which are growing uncontrollably.
They can be called immortal. The X ray structure of the E. coli tryptophan repressor has been determined to high resolution. The crystal form obtained is a tetramer. The functional form is the dimer. From the website for this class, you can access a website form which you can download the RasMol program.
