I am trying to complete an assignment about DNA, and the following questions are nowhere to be found in my textbook/notes nor in any easy-to-understand journals! so any help would be greatly appreciated - The difference between DNA and RNA that allows them to be separated... I know that DNA has a deoxy portion on the ribose, and is double stranded instead of single, but is this what allows it to be soluble and separable in certain solvents that RNA cant? and if so how exactly? - what base does to DNA and how it affects its viscosity if at all...does it base hydrolyze it or? this one's really confusing me - what acid does to DNA and how it affects its viscosity if at all...again same as above...really confused - DNAse affect on visocity of DNA ... this one I know that DNase cleaves and cuts the DNA into parts, and that it reduces its viscosity...but how? it is simply because the molecule is in many smaller parts so it can flow faster or something like that? - how is DNA precipitated....is it like denatured with certain substances? or is there some sort of charge issue? Of course I dont expect input on all of these, but any would be really helpful. Thanks!!!
