of genomic DNA from animal tissues Introduction A rapid expansion of DNA analysis in medical‚ biotechnological and basic research has created the need for simple and efficient commercial methods for isolating genomic DNA. Many different methods and technologies are available for the isolation of genomic DNA. In general‚ all methods involve disruption and lysis of the starting material followed by the removal of proteins and other contaminants and finally recovery of the DNA. Removal of

EXTRACTION OF COPPER FROM OXIDISED COPPER ORE Aim: To analyse how copper is obtained from oxidised copper ore using the processes of leaching‚ solid-liquid separation‚ displacing and electrowinning. Method: Refer to ‘Extraction of Copper from oxidised Copper Ore’ document pages 1-2 Results: Leaching: The blue particles in the copper ore which is copper was dissolved in the sulphuric acid and the solution turned into a blue colour. There was also sediment that was floating around

DNA profiling DNA profiling (also called DNA testing‚ DNA typing‚ or genetic fingerprinting) is a technique employed by forensic scientists to assist in the identification of individuals on the basis of their respective DNA profiles. DNA profiles are encrypted sets of numbers that reflect a person’s DNA makeup‚ which can also be used as the person’s identifier. DNA profiling should not be confused with full genome sequencing. It is used in‚ for example‚ parental testing and rape investigation

The DNA Identification Act of 1994 authorized the establishment of a national index of: (1) DNA identification records of persons convicted of crimes‚ (2) analyses of DNA samples recovered from crime scenes‚ and (3) analyses of DNA samples recovered from unidentified human remains. In addition‚ it specified several standards for those laboratories that contribute profiles to the national index system‚ including proficiency testing requirements for DNA analysts and privacy protection standards related

Forensic DNA testing In Today’s forensic DNA testing is used all around the world to catch criminals. Forensic DNA testing is able to catch suspects and analyze their data correctly to be able to identify their suspect and be sure to identify their suspect and be sure it is the right person. DNA testing is 100% accurate and is the most effective type of testing there is and can change many lives such as criminals‚ fathers and children. Before forensic DNA testing

serial dilution of the DNA concentration. As shown by the picture‚ only the first drop of the DNA/EtBr mixture for the DNA standards fluoresce brightly under the UV light‚ while the other spots for both the DNA standards and the unknown DNA standards were all dimly fluoresce. This was due to pipetting error; the tip of the pipette did not touch the liquid (TE) in the micro-centrifuge‚ so no DNA standards were transferred into the liquid. In the first row (known DNA standards)‚ the DNA was inserted into
