hey there...

can someone pls help me with this question...i read it and I dont understand a word of it...

a newly-isolated dna sample had an [email protected] of 0.8 for a 0.02mg.ml-1 soln. when 1ml of this soln was mixed with 1ml of 0.5M HCl and hydrolysed for 6hr, the resulting soln had an [email protected] of 0.53. if the original soln (0.02mg.ml-1) was heated to 100 degrees celsius for 5min and then quickly cooled wat [email protected] wld you expect to measure at a 1 in 5 dilation...
