Sequencing By Ligation Animation

National human genome research institute 118849 views. The sequencing method developed by fred sanger forms the basis of automated cycle sequencing reactions today. This is a combination of concepts we covered in the two previous pages.

These processes will be illustrated with 3d animations as well as quiz questions.

Sequencing by ligation animation. Virtual labs on frontiers in biochemistry. Sequencing by ligation is a dna sequencing method that harnesses the mismatch sensitivity of dna ligase to determine the underlying sequence of nucleotides in a given dna sequence ho et al 2011platforms based on this method use a pool of oligonucleotide probes of varying lengths which are labeled with fluorescent tags depending on the nucleotide to be determined. Fluorescent dyes are added to the reactions and a laser within an automated dna sequencing machine is used to analyze the dna fragments produced. Next generation sequencing animation.

Data processing and analysis. Solid sequencing by oligonucleotide ligation and detection is a next generation dna sequencing technology developed by life technologies and has been commercially available since 2006. Church at harvard medical school is a sequencing technique that uses paired tag library emulsion pcr to amplify the target dna and sequencing by ligation to detect dna bases. You will then proceed to the sequencing machine where you will perform cluster generation followed by the sequencing reaction and data collection.

Youtube dede lamme sequencing by ligation duration. Note that this is the opposite direction to polymerase based sequencing methods. The 3 5 direction is more efficient for doing multiple cycles of ligation. This animation is also available as video.

The library preparation method is straightforward. This next generation technology generates 10 8 10 9 small sequence reads at one time. It uses 2 base encoding to decode the raw data generated by the sequencing platform into sequence data. The ligation sequencing kit offers a flexible method of preparing sequencing libraries from dsdna eg.

After completing the sequencing procedure you will acquire the data outcome as a fastq. Sequencing by ligation can proceed in either direction either 5 3 or 3 5 depending on which end of the probe oligonucleotides are blocked by the label. Polony sequencing developed by george m.
