Fantastico Exame DNA por saliva (raspado bucal ou swab)
voir la vidéoDemonstração de Coleta indolor de Células da Boca no Fantástico (Rede Globo) para fins de Exame de DNA. No dia 30/7/2006 o Fantastico realizou uma matéria com algumas personalidades afim de checar, através de exame de DNA, o grau de parentesco que eles possuíam com indígenas. O método de coleta do DNA foi o de saliva (também conhecido como raspado bucal ou "swab"), em que os participantes coletam, através de uma pequena escova, células da buchecha e inserem dentro de um pequeno frasco com substância conservadora do DNA, ou seja, o mesmo método usado para coleta de material biológico para fins de Investigação de Paternidade: simples, indolor, rápido e seguro. Depois de realizado este procedimento, o Kit-DNA é enviado imediatamente para o laboratório onde se dará o início do processo de investigação de paternidade por análise de DNA. Para mais Informações à respeito de Teste de Paternidade por saliva, ligue para: (21) 3010-9696 / (21) 2235-2923 / (11) 3010-9397 / (19) 3119-4844, ou mande um e-mail para: "contato@biofutura.com.br" [ go to Youtube.com ]

DNA Test Methods - DNA Sanger Sequencing
voir la vidéoView the full Interactive Tutorial at: www.phgfoundation.org Once a piece of DNA has been amplified, it can be sequenced. In this process, four reaction mixtures are set up, each one including: 1. DNA to be sequenced 2. DNA polymerase 3. A supply of nucleotides (A, C, G and T) 4. A small amount of a labelled chain-terminating variant of one of the four nucleotides. The enzyme DNA polymerase incorporates a chain-terminating variant at random, eventually ending the chain at every possible nucleotide position over a few hundred bases. The products of the reaction mixtures are run on an electrophoresis gel, where the sequence can be deduced by reading from the smallest to the largest piece. If different fluorescent labels are used for the variant bases, sequencing can all be done in one single reaction, the bands can be detected and the sequence read out automatically. The entire process of DNA sample preparation and sequencing is now highly automated, a development that has been essential for the timely and cost-effective completion of the human genome project.

DNA Test Methods - Hybridisation
voir la vidéoView the full Interactive Tutorial at: www.phgfoundation.org Often, a particular piece of DNA (or RNA) of interest needs to be detected in a mixture containing many pieces with different sequences. One way to do this is by hybridisation. Hybridisation refers to the process in which two complementary pieces of DNA (or a piece of DNA and a piece of RNA) anneal to form a double-stranded molecule. The piece of DNA or RNA used to detect complementary sequences is often called a probe. If the probe is labelled, for example by making it radioactive or fluorescent, then any pieces of DNA or RNA that it hybridises to will also be labelled and can be detected. Before it can be used for hybridisation, a double-stranded DNA molecule must be separated into single-stranded DNA molecules, or denatured. Denaturing is usually achieved by heating the sample; when it is cooled, the resulting single-stranded molecules will hybridise to complementary molecules in the mixture, including those of the labelled probe.

DNA Test Methods - The Polymerase Chain Reaction
voir la vidéoView the full Interactive Tutorial at: www.phgfoundation.org The polymerase chain reaction, or PCR, is a crucial method for exponentially increasing the amount of a specific DNA sequence. PCR is a cyclic process controlled by the temperature of the reaction mixture. First, the temperature is raised to 95°C (205°F), causing the template DNA to separate (denature). The temperature is then decreased to around 50°C (122°F), allowing short primer pieces of DNA to hybridise to each strand of the template at opposite ends of the sequence to be amplified. The thermostable enzyme Taq (a DNA polymerase that is active at high temperatures) then binds to and extends the primers at an intermediate temperature of 72°C (162°F), so that two new double-stranded copies of the template are made. This cyclic process of separating DNA strands, copying and reannealing the daughter strands is repeated multiple times to increase the numbers of DNA product. [ go to Youtube.com ]

The DNA Test
voir la vidéoA strong amount of emotion and affection existed between Henry (Van Vicker) and Diane (Juliet Ibrahim), until jealousy tore them apart. Paranoia and aggression towards Juliet Ibrahim overtakes Henry's natural love for her. His suspicious of any man that comes near her leads him to call off their planned wedding and to even deny his unborn child. The only way for Diane to prove her faithfulness is through a DNA test. The plot thickens as the doctor performing the DNA test seeks to take advantage of the situation for his own selfish interest. Find out the fate of this heart broken mother and her unborn child.
