However, Sci/Tech Buzz Sat, 24 Oct 2009 19:22:33 +0000 Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms ... Sci/Tech Buzz Sat, 24 Oct 2009 19:25:01 +0000 A typical human cell contains about 150,000 bases that have suffered oxidative damage.[58] Of these oxidative lesions, the most dangerous are double-strand breaks, as these are difficult to repair and can produce point mutations, insertions and deletions from the DNA sequence, as well as chromosomal translocations. Sci/Tech Buzz Sat, 24 Oct 2009 19:27:42 +0000 A typical human cell contains about 150,000 bases that have suffered oxidative damage.well DNA is one of the most important human organism Sci/Tech Buzz Sat, 24 Oct 2009 19:28:43 +0000 All the functions of DNA depend on interactions with proteins. These protein interactions can be non-specific, or the protein can bind specifically to a single DNA sequence. Enzymes can also bind to DNA and of these, the polymerases that copy the DNA base sequence in transcription and DNA replication are particularly important. Sci/Tech Buzz Sat, 24 Oct 2009 19:29:48 +0000 Methods have been developed to purify DNA from organisms. Sci/Tech Buzz Sat, 24 Oct 2009 19:30:43 +0000 People convicted of certain types of crimes may be required to provide a sample of DNA for a database. This has helped investigators solve old cases where only a DNA sample was obtained from the scene Sci/Tech Buzz Sat, 24 Oct 2009 19:31:23 +0000 DNA profiling can also be used to identify victims of mass casualty accidents Sci/Tech Buzz Sat, 24 Oct 2009 19:31:55 +0000 On the other hand, many convicted people have been released from prison on the basis of DNA techniques, which were not available when a crime had originally been committed. Sci/Tech Buzz Sat, 24 Oct 2009 19:32:46 +0000 wel DNA techniques are further being modernised so that cure for cancer becomes easier Sci/Tech Buzz Sat, 24 Oct 2009 19:33:42 +0000 DNA has also been used to look at modern family relationships, such as establishing family relationships between the descendants BrownPenguin.com
