This document discusses different methods of DNA isolation including the Maxwell 16 Plant DNA Kit method, spin column method, and CTAB method. It explains the structure of DNA and importance of DNA extraction for uses such as genetic testing, body identification, and analysis of forensic evidence. DNA can be stored long term at temperatures of -20属C, -80属C, -196属C or dried at room temperature. Isolated DNA has applications in understanding plant individuality, plant modification, forensic analysis, and solving historical puzzles.

Maxwell速 16 Plant DNA Kit Method
An easy method efficient
Automated purification of
genomic DNA from plant tissue
samples.
9. Spin column Method
It is a solid phase extraction method
Quickly purify nucleic acids.
Nucleic acid will bind to the solid phase of silica under certain conditions.
12. Procedure for CTAB method
Sample extract
CATB Centrifuge Carbohydrates,
proteins, etc.
Nucleic acid-
CTAB complex
DNA
Precipitated Nucleic
acid-CTAB complex
13. Why DNA Extraction?
Genetic Testing
Body Identification
Analysis of Forensic Evidence
14. There are four temperature based strategies for long term DNA
conservation. These are storage at:
-20属 C
-80属 C
-196属 C
Dried, at room temperature
Store DNA in dry state, reduces molecular mobility and inhibits the
depurination, depyrimidination, deamination and hydrolytic
The DNA immobilized on FDA cards is amenable to PCR after 17
years storage.
DNA in aqueous phase is stored under slightly basic conditions.
At -196属 C, DNA is maintained in a vitreous state
General consideration for DNA storage:
15. Understanding Individuality of Plants
Using genetic information of DNA for plant modification
Use in forensic analysis
Use to solve historical puzzle
