Engineering Mini project: DNA COMPUTERS
After seven days of intensive laboratory work, Adleman's test-tube contained the answer to the problem, subsequently visible as a series of dark bands on a DNA sequencing gel. On the face of it, it might hardly seem worth the bother, especially as Adleman already knew the answer before he started the experiment. But this was much more than a curious laboratory stunt. During the initial 'linking-up' stage of the process, Adleman's test-tube computer effectively performed an astonishing 10^14 calculations. And it did so with the consumption of only a tiny amount of energy, and in a tiny [more...]

Can I use sheared genomic DNA as starting material of bacterial ...
My question is whether initially sheared genomic dna can be safely used for genome sequencing and assembly by 454 technology. By 'initially', I mean genomic DNA was sheared during extraction process. I attach gel image of my genomic dna samples (marker is lambda dna digested with EcoRI and HindIII). Although I know that dna fragmentation step is involved in standard genome sequencing by GS FLX titanium, I am concerned because I think it might be possible that shearing during extraction can affect randomness of standard fragmentation step and so on. Thanks in [more...]

What are gel elctrophoresis and DNA microarray? How is each used ...
Question by neonpinkispink: What are gel elctrophoresis and DNA microarray? How is each used in the study of genetics? Best answer: Answer by brainybroad269 Gel electrophoresis is the use of a gel to separate pieces of DNA (or RNA, or protein) under an electric field. The simplest form separates pieces by size. More complex (2-dimensional) techniques can separate proteins by size and charge. A DNA microarray is a collection of short DNA sequences (“oligonucleotides”) immobilized on a piece of glass or other support (the “gene chip”). When you incubate the chip with your experimental [more...]

Dr. Pandey “pulls off” new DNA sequencing method
The current method to sequence DNA is called gel-electrophoresis. This process is very costly and time consuming. However, Dr. Pandey and his research team have proposed a way to make DNA sequencing far easier and cheaper than the current method. For those of you scratching your heads and wondering what the purpose of DNA sequencing could possibly be, imagine in the futurew going to the doctor and getting customized medicine just for you based on your DNA. This medicine would do exactly what it needed to in order to fix your problem because it was made specifically for you and only you. [more...]

Sequenziamento del DNA- Prima generazione (metodo Sanger) « my GenomiX

Il DNA (o acido deossiribonucleico) è una molecola che ha l’aspetto di una doppia elica formata da due catene di nucleotidi. I nucleotidi sono piccole molecole costituite da un gruppo fosfato, uno zucchero (deossiribosio) e una base azotata; mentre le prime due componenti sono sempre uguali e costituiscono l’ossatura della doppia elica, le basi azotate esistono in quattro “versioni” differenti.

Abstract TopThe majority of studies employing short tandem repeats (STRs) require investigation of several of these genetic markers. As such, we demonstrate the feasibility of the trinucleotide threading (TnT) approach for scalable analysis of STRs. The TnT method represents a parallel amplification alternative that addresses the obstacles associated with multiplex PCR. In this study, analysis of the STR fragments was performed with capillary gel electrophoresis; however, it should be possible to combine our approach with the massive 454 sequencing platform to considerably increase the [more...]

Mixtures of DNA fragments were separated by size using gel electrophoresis and the bases were identified and entered into a computer through manual techniques. Automated DNA sequencing instruments arrived later. These instruments made DNA sequencing thousands of times more efficient by detecting fluorescently labeled fragments and sending the information directly to a computer (2).

Then, this band is excised out from an agarose or acrylamide gel and purified by using either: binding and elution from glass or silica particles, DEAE-cellulose membranes, "crush and soak method", electroelution or very often expensive commercial purification kits.
