Hi I'm doing a project on DNA fingerprinting for my XI finals .Could you tell me of some good sites I could look up on the net?Names of a few books would also be great help (but I'm not sure I can get my hands on them) Thanks

What happens when point mutation occurs in the somatic cell of a person?Of course the mutation can't be transferred,but does it spread to other cells?and does it manifest itself in the affected individual? I'm sorry if this is a stupid question but I've asked two of my teachers and they don't seem to get my question.

I'd definitely pick the maid.Thats about the only chore that we have to do by ourselves at kolkata.

I'd have thought as it is semi-permeable then, yes it will occur because the chemical potential will be different on both sides...

OK. Think I get you.Thanks. But I'm not really confident about being able to explain chemical potential.Could you help me out?

Its pure alcohol. er....whats an azeotrope?

He thinks that because the solvents are different they shouldn't get through.

But my argument is that as the two liquids are soluble in each other osmosis should occur.But I can't convince him.I'm trying to be more technical...

Thanks

Hi.I'm new here.I'm in a bit of a mess with my bio teacher.Here's my question-- Say I take a U-tube and fill one limb with pure water and the other with pure alcohol.They are seperated by a semi-permeable membrane.Shall osmosis take place?

My teacher thinks it won't but I believe it will.Could you sort it out.

Thanks!!!

Hi.I'm Shabnam.I'm a bit mad about science.It's great to come here and meet you all.
