i need some good information on dna isolation,please.?

The stages of DNA isolation include\n    1) homogenization of thymus in a buffered isotonic sucrose-detergent solution\n    2) increasing the osmolarity with saline\n    3) centrifugation to remove cellular debris\n    4) decantation of the supernatant into a clean beaker\n    5) precipitation of the DNA by layering cold ethanol on the top of the supernatant\n    6) spooling of the precipitated DNA\n\nCheck out the website... im sure thats pretty much all you'll need :)\n\nhttp://www.biology.clc.uc.edu/fankhauser/Labs/Genetics/DNA_Isolation/Thymus_DNA.htm

although all the answers represent components of eukaryotic genomes, e is the best answer\n\nhere is a link with some additonal info\n\nhttp://www.biologynews.net/archives/2005/05/02/scientists_track_stealth_dna_elements_in_primate_evolution.html

DNA comparison by electrophoresis. I've seen kits available in school divisions for science classes. On a similar note: paper chromatography to check if the composition of ink between samples are same or different.

It's about the discovery of DNA and what it is made up of.

DNA can trace a long ways back. There are "markers" that persons of the same relation will carrying. one set of markers is for your mothers side and another from your fathers side. if i rememeber right the mothers side is a little eaiser to trace back. :)

Do refer to websites, such as Wikipedia, Vivisimo or Google; you will find countless articles, links and so on. Start with any scientific term, such as 'chromosome' and it will get you somewhere. Kimballs Biology Pages are a wonderful bet too.

Good God man you are on the net, you have more information than you know what to do with right at your finger tips. Go to Yahoo's main page and type genetics into the search bar.

http://biology.about.com/library/howto/htcandydna.htm\nThis is how to build a DNA model using candy.  I got it as the second rated site in a google search of "DNA model"  If you don't like their suggestions, you can use this search to find other models.

Go to the source links I provide below.  They should be helpful and informative.

You can find practical information from Qiagen website if you use their kits which are quite popular these days.  \n\nIt depends on which methods you use for isolation.  The alkali lysis (see link below) was commonly used to rupture bacteria.  Plasmid DNA (smaller in size and more soluble) is separated from baterial genomic DNA (larger and less soluble).  The plasmid DNA is then separate from proteins by phenol extraction where the proteins are removed to the phenol phase while plasmid DNA stays in the aquous phase.  The plasmid DNA is then precipated with ethanol to complete the purification.\n\nQiagen's kit and others overcome the use of phenol (which is toxic and smelly) by using a solid phase that bind DNA to seperate the contaminating proteins.  The DNA is later eluted from the solid phase to complete the purification.\n\nHere are additional links:\nhttp://biotech.biology.arizona.edu/labs/DNA_isolation_plasmid.html\nThe concept of alkali lysis method of plasmid DNA isolation is shown here:\nhttp://a32.lehman.cuny.edu/molbio_course/plasmid_protocol.htm
